ARTICLE - CHASING THE DRAGON..AND THE MONKEY...AND THE ROOSTER

Chasing the Dragon...and the Monkey and the Rooster

Updated: 2012-01-29 10:22

 

By Han Bingbin (China Daily)

 The Chinese zodiac's 12 animal signs are always popular symbols in both East and West. And when the Lunar New Year arrives, enthusiasts all over the world are eager to get their hands on the best collections. This year, the focus is on stamps. Han Bingbin reports. 

 As a zodiac mascot, the dragon soars above its peers as the symbol of the year. Compared to the rabbit (which just gave up its one-year reign), the ox, rat, snake, monkey, pig, goat, rooster, tiger, horse and dog, the dragon is a notch above. Why? Because it is the only mystical beast in the zodiac barnyard and it also bears the aura of aristocracy. Its fire-breathing looks sometimes give rise to a misunderstanding. For example, the official dragon stamp released to commemorate the Spring Festival this year was criticized for its ferocious demeanor. Chinese netizens were quick to criticize the image on the stamp as "overbearing" and asked if it should not have been more benign. 

 

The stamp's creator, designer Chen Shaohua defended his design online in his blog, carefully avoiding confrontation by refusing media interviews. The dragon's role in mythology was to ward off evil, he says. As a deified image passed down through generations, it deserves the respect and dignity of preserving its legendary reputation, and should not be subjected to arbitrary changes.
Chen is no greenhorn. He had previously designed four zodiac stamps over the last 20 years.
The selection committee this year had requested a younger, more modern dragon, he said on his blog, but Chen justified his design saying his dragon image was inspired by the patterns on the imperial Qing robes and Nine Dragon Wall. He said it symbolized China's growing confidence and importance on the world stage.
Chen probably learned from past experience. In 2010, his stamp design for the Year of the Tiger featured an affable-looking mother tiger sitting with her cub. The design lost to a rival entry that showed a youthful and energetic tiger, standing hands on hips.
However, collectors are unfazed by the chatter online. The negative comments have had no effect on sales. All over China, people lined up in the chill of winter to snap up the dragon stamps. When the stamps sold out at the post offices and official sources, the private market starting getting active and price hikes sent the value of the stamps soaring like, well, dragons.
By early January, a set of 20 dragon stamps was selling for as much as 350 yuan ($55) at Beijing's Madian Memorabilia Market, the biggest stamp market in Asia, compared with the original price of 24 yuan from the post office. Experts say many collectors are already prepared to pay more.
"For the price to go up to 500 yuan is a piece of cake," says Yu Yanping, a senior stamp dealer at Madian. He says the dragon stamps from the last two cycles have performed really well in the market. (The zodiac cycle is 12 years, so the last two Dragon years were in 2000 and 1988.)
A set of 80 dragon stamps from 1988 sells for about 3,000 yuan now, while a set of 32 stamps from 2000 is valued at more than 5,000 yuan.
Geng Shouzhong, author of the international award-winning Encyclopedia Knowledge of Chinese Philately, explains that in 2000, the Year of the Dragon coincided with a significant year in the Gregorian calendar, and many Chinese used the dragon stamps to post letters to mark the occasion. That left a limited number of mint-condition stamps, those valued most by traders and collectors.
Geng, with his 60 years of stamp-collecting experience, believes the price hike of the newly released dragon stamps is a mirage, as it is still untested by time.
Above all, Geng says the ultimate value of the stamp depends on how many were produced and how many tradable units are left over time.
These are the two main factors that help create valuable "legendary" stamps.
The monkey zodiac stamp released in 1980 was the first in the series released in China. Each monkey stamp can now fetch more than 10,000 yuan, and a complete set of 80 stamps will easily cost more than one million yuan.
It was at a time when the country was recovering from a "cultural revolution" (1966-76) and stamp collectors were only beginning to start up their hobby again. For that reason, the print-run was kept conservative and was to be only 6 million.
However, printing ink ran out sooner than expected and as a result, only 5 million monkey zodiac stamps were printed, Geng remembers. After further eliminating stamps that were of poor quality, the number of monkey zodiac stamps that finally showed up on the market was only about 4 million - the lowest number in the zodiac series to this day.
Since then, as public demands for these annual collectibles increased, the print numbers went up in response.
Between 1986 and 1991, the number stayed at around 120 million pieces. In 1992, the start of the second cycle of zodiac stamps, it increased to more than 200 million. In 1993, the Year of the Rooster, 250 million stamps were produced, effectively making that zodiac stamp the least valuable in the market today, according to Geng.
As public interest in zodiac stamps cooled, less stamps were printed in subsequent years, right up till 2003, the Year of the Goat. Only 38 million stamps were issued that year.
Yu from Madian Memorabilia Market says a set of 2003 Goat-Year stamps has now risen to about 1,700 yuan, appreciating from 80 yuan just two years ago.
Geng says that for those who collect stamps as an investment, there are still ways to observe the rise and fall of the market value. But the old collector frets that the monetary drivers overshadow the artistic intentions.
Stamp collecting is ultimately for the art, rather than for the money, he muses.
China Post seems to agree and each year, it invites renowned Chinese artists to submit designs for the zodiac stamps. Their contributions are assessed by a committee of experts and officials.
In the early years, it was a sacred task when an artist was asked to design the zodiac stamps. Early designers of the first zodiac stamps included prominent names such as master painter and sculptor Han Meilin and Zhou Lingzhao. The latter is the artist who created the third version of Chairman Mao Zedong's portrait, which was used for the founding ceremony of the People's Republic of China on Oct 1, 1949.
In the early days, too, it was more art than technology. Stamp printing used a technology that combined engraving (where the image was first incised by hand and then printed onto the stamps) and heliography. One advantage of that technology, Geng says, is that the image came out really vivid and stereoscopic.
For example, you can clearly see the detailed lines on the monkey fur. The monkey's facial expression was equally detailed and true to life, with the gilded eye a particular highlight.
For Yang Yao, a young but experienced stamp collector who works at China Post's Jiangsu Branch, this old-fashioned technology is what distinguishes the zodiac stamps from those issued by other countries.
In 1950 Japan was the first country to issue zodiac stamps, and now more than 90 countries regularly issue zodiac stamps. Many of these, especially Western countries, commission Chinese artists for the designs.
China's unique stamp-making technology still sets its zodiac stamps apart, for their "authentic Chinese flavor", Yang says.
But Geng grows nostalgic. The latest and current series of zodiac stamps has already abandoned part of the old method and uses only a heliographic (photographic) process, to minimize damage to stamps during printing.
Geng is updating his philatelic encyclopedia, and he notes that all the background knowledge about art and history is what makes it fun for the stamp collector. It requires an investment of time and patience to read and study, something he and his wife have been doing for decades.
"As the old adage goes, stamp collecting increases knowledge. This little postage stamp is truly a small encyclopedia," he says.

Zoologger: The monkey that really gets brotherly love

Habitat: Tropical forests in Panama and Columbia, hanging with the family
They're cute, they're helpful, they'll carry your babies. What's more, several males are happy to club together in order to serve a single female. Female Geoffroy's tamarins sure do have it easy.
The monkeys live in groups of three to nine, in which multiple adult males mate with a single breeding female and then cooperate to raise her young. This mating system, called polyandry, occurs in less than 1 per cent of bird species, and is even rarer in mammals.
Here's why: if you're a male, you can make lots of sperm cheaply and quickly, so to maximise your chances of reproducing, it makes sense to mate with as many females as possible.
Females, on the other hand, invest energy in making few eggs and have to bear the energetic costs of pregnancy. They evolve to be picky, choosing only the best males to fertilise their eggs. So you might expect mating systems where males mate with many females, rather than the other way around. Not in tamarins.
Male Geoffroy's tamarins provide everything an infant wants except milk. They carry the young more than the females do, which is a considerable burden as infants weigh 25 per cent of adult body mass at birth and bulk up to 50 per cent before they can move independently at 10 weeks of age. Carrying the youngsters slows males down as they forage for fruit and insects, and makes them vulnerable to predators. Which raises the question: why care for offspring that are not your own?

Paternity test

Sam Díaz-Muñoz, then at the University of California, Berkeley, observed six groups of wild tamarins in two rainforest sites in Panama and Columbia to find out.
He tested two possibilities. If males were closely related, they would gain an indirect benefit by helping related offspring – they would ensure that genes they shared with the father of the infants were passed on to the next generation. Or males might cooperate simply because if they stick around they could have a reasonable chance of siring offspring themselves.
Díaz-Muñoz needed to collect DNA samples to establish the groups' family trees. But a quirk of tamarin biology complicated the process.

Extreme bromance

80 per cent of tamarin births are fraternal (non-identical) twins, formed from two sperm fertilising two separate eggs. As fraternal twins come from different eggs and sperm, they have different DNA profiles.
But even though tamarin twins develop as separate embryos, they grow within the same chorion – the outermost membrane surrounding the embryo, which contributes to the placenta.
Blood vessels connect the embryos within the chorion and exchange cells between them early in development, so even though most parts of the two embryos have their own unique DNA profile, their blood profile is identical.
"People starting doing genotyping and found that with blood you get an identical profile," says Díaz-Muñoz.
The solution? "If you go to tissue types that are blood-cell-free – such as hair – then you get different DNA fingerprints," says Díaz-Muñoz.

Keep it in the family

DNA showed that males were related at the levels expected for brothers or half-brothers, or fathers and sons. But males in some groups also shared paternity, even within the same litter – there were fraternal twins with different fathers.
Males walk a balance between the indirect genetic benefits they enjoy from caring for young animals they are related to, and the direct benefits of siring their own offspring, says Díaz-Muñoz.

Ejaculates at dawn

It's not all happy families, though. Tamarins undergo seasonal change in testes size, with very large testes for their body mass. Usually one group member has much larger testes than the other males. So though males cooperate, their sperm still competes within the female to fertilise her eggs – the male with the biggest ejaculate may sire the most offspring.
"If you have to share matings, you might as well do it with someone you're related to," says Díaz-Muñoz. "And then you duke it out in the sperm competition."
Outside of tamarins and their close cousins the marmosets, only one other primate practises polyandry: humans. In the ethnically Tibetan Nyimba population of north-western Nepal, brothers share wives, though marriages can break down when there are too many brothers.
Perhaps tamarins have something to teach us about brotherly love. Captive tamarins spend most of their time in monogamous pairs, says Díaz-Muñoz. "You can keep them in trios – but only if they're related."
