梁思成
Although Ming dynasty (1368–1644) authors compared the bridge to "a new moon rising above the clouds" and "a long rainbow hanging on a mountain waterfall", it later fell into obscurity. When Professor Liang Sicheng of Tsinghua University rediscovered the bridge on a field exploration of ancient architecture in Hebei province, he made detailed measurements and published a report and drawing, after which the bridge became world-famous.
