Wind-and-Rain Bridge Builder Yang Siyu

JIAO FENG

EACH of Chinas ethnic minori- ties has a discrete building style that immortalizes its culture and anchors its esthetics. That of the Dong ethnic minority, who live mainly in southern Chinas Guangxi Zhuang Autonomous Region and Guizhou and Hunan provinces, is the windand-rain bridge – a roofed, sometimes walled multi-tiered structure of curved eaves and pavilions. It is distinct from other Chinese bridges by virtue of the defining elements of pagoda, pavilion and gate tower combined through a conventional configuration. These auxiliaries are both ornamental and functional as they provide shelter during south Chinas frequent heavy rains and strong winds.

Yang Siyu masterminded construction of the wind-and-rain bridges and drum tower in Linxi Township, Sanjiang Dong Autonomous County in northern Guangxi. Born in 1955 to a family of carpenters and bridge builders, Yang began learning his trade from his father at age 13. He has over the past four decades de- signed six wind-and-rain bridges, more than 100 stilted homes, eight drum towers (including one of 27 storeys) and 20-odd pavilions, as well as 2,680 models of bridges and drum towers. In 2007 Yang was nominated as an inheritor of the intangible heritage of traditional Dong wooden-structure architectures.

Intangible Plans

The components of such traditional Dong wooden structures as bridges, drum towers, drama stages and waterwheels fit together through tenons and mortises rather than nails or screws. Despite the precision this type of design demands, the builder embarks on each project guided solely by his mentally conceived plan. Nothing is committed to paper. Dong architects also have the amazing ability to calculate complex mathematical computations in their head, the results of which they jot down on a bamboo pole – their main measuring tool – in an esoteric script.

However obsolete it might seem to the architectural establishment, this centuriesold practice is highly efficient. When, back in 1983, the wooden Chengyang Wind-and-Rain Bridge, built in 1916 and main landmark of Sanjiang County, collapsed under heavy rain, a team of college-trained architects was called in to restore it. In the dismantling process each piece was coded, but reassembling the bridges thousands of variously sized parts was agonizingly slow because the team had no guide as to their proper location.

They eventually called on Yang Siyu and his father for help. The pair immediately set off at the head of a logging team to the nearby mountains. There they cut down and shaped timber to replace the ravaged bridges thousands of missing parts, mentally calculating the size of each raft, purlin and pillar. Within two weeks they had prepared the needed timber. Without consulting the teams carefully compiled codes, father and son then oversaw the piecing together of the salvaged parts and their splicing with the new components. It was only when the bridge stood exactly as it had for the past century that these formally-trained architects were able to finish their blueprint. This achievement brought Yang senior and junior instant fame in Chinas architectural sector.

Sons for Bridges

The Yangs have an affinity with the Chengyang Bridge. Yang Siyus grandfather, Yang Tangfu, liquidated most of his assets, including farmland, to help fund its construction.

Bridges have a special significance for residents in Sanjiang County. Local Dong residents believe that a bridge spans the river separating the temporal and nether worlds, and that contributing to bridge building brings rewards in the afterlife and blessings on offspring. This explains why the small county of Sanjiang is strewn with more than 100 bridges, and why bridge building shows no abatement.

This ancient belief turned out to be true for Yang Tangfu. The sole male heir in his family after three generations, he did not himself have a child until many years after marrying. His first son Yang Shanren was born soon after the Chengyang Bridge was completed, and his brood steadily expanded in tandem with his funding of more bridges. Yang Shanren later had five sons, two daughters and a dozen grandchildren. Of the five that inherited the family bridge building business, Yang Siyu is the most adept.

“My father felt a strong bond with the Chengyang Bridge, and would shed tears on every visit, so I refurbish it every 10 years. When the 1993 repair project ran out of government funding, I covered the shortfall by selling half of the tiles on my roof.A tarpaulin covered my home for more than a year after,” Yang Siyu recalled.

The bridge building passion has been ingrained in Dong life for millennia. The wooden structure spanning every river in their environs represents a celebration of their faith and a monument to their charitable spirit.

Mini-masterpiece

When Hong Kong was returned to China in 1997, Guangxi Zhuang Autonomous Region decided to present a mini replica of the Chengyang Bridge as a gift to the government of Hong Kong Special Administrative Region. On hearing the news, Yang Siyu applied to the relevant government department, telling them he was willing to carry out this task for free. Yangs application was accepted barely one month before the delivery date. To win this race against time Yang mobilized his whole family, including Yangs 75-year-old father Yang Shanren, and his teenage children. After three weeks of working day and night, stopping only for the occasional bite to eat, the Yangs came up with an exact replica of the Chengyang Bridge. Like the original, it consists of more than 9,800 parts, the longest 2.5 meters and the shortest just a few millimeters long, connected, according to tradition, solely by tenon and mortise joints. More than 100,000 millet-sized hand-carved tiles shingle its roof.

After undergoing a close scrutiny, Yangs work achieved the highest score of all other submissions. It was then shipped to Hong Kong for an exhibition, where local architects marveled at its complexity and delicacy. One journeyed to Yang Siyus home to consult him on Dong architectural culture.

Yang now mentors more than 100 apprentices including his two sons. Although committed to handing down this archaic ethnic craft, he has another plan in mind for the future. An aficionado of the Dong Grand Song – unaccompanied folk acapella singing – he hopes to establish a troupe and build a theater by Chengyang Bridge with a stage on the first floor and a restaurant serving Dong food on the second. As Yang Siyu said,“It will also offer local villagers a venue to meet and enjoy theatrical entertainment.”
