Driving more than 300 kilometers from Beijing to the West and south, we arrived at Zhaoxian County, Shijiazhuang, where we will visit the world-famous ancient bridge, Zhaozhou Bridge. Zhaozhou Bridge Scenic Area is not large. When entering the main entrance, a shadow wall comes into view. Mr. Mao Yisheng's words and relief stories tell the legend and history of the ancient bridge. We carefully looked, this is not included in the primary school Chinese textbook paragraph. Around the shadow wall, the folk song of cattle herding brings us to Baxian Avenue. According to legend, on the day the bridge was built, Zhang Guolao, one of the eight immortals, was riding his donkey upside down with the sun, moon and stars, accompanied by a fairy, Chaiwang. King Chai pushed a wheelbarrow carrying five mountains and three mountains. The purpose of their trip was to test the load-bearing capacity of Shiqiao. Crossing Baxian Avenue, Shiqiao, in her 1400's, appeared in front of her eyes. Rainbow-like reflections in the water form an olive shape with real stone arches. On an arch bridge with a big rainbow, four stone arches with small rainbows are carried on the shoulders. The advantages of this design are not only beautiful, but also solving the problems of self-weight and flood discharge. Walking on the bridge, he stroked the fine stone carvings on both sides of the railings with his hands. Most of the carvings were made of dragons. The ancients used dragons, the totem of the Chinese nation, to protect the stone bridge and the life on both sides of the river. I wonder if the ferocious flood that happened in the 1960s, when the water level rose close to the bridge deck, saw the dragon in the middle of the bridge and decided to withdraw. No wonder the old bridge can survive eight earthquakes and still stand up intact after nearly 10 floods. A rut and a small oval pit in the center of the bridge, together with the footprints of donkeys, seem to confirm to us that the story of Chai Wang and Zhang Guolao testing load-bearing is real. Through the joy of acceptance, Luban forgot to name the bridge, and the local people gave him a small name - Dashiqiao. One day 400 years later, a great man came, Song Zhezhong. After he passed this practical and beautiful stone bridge, Long Yan Dayue named it Anji Bridge. From then on, Zhaoxian Dashi Bridge immediately became famous in Jiuzhou. A thousand years later, in 1933, another great man came. He was Liang Sicheng, a famous architect in modern China. The Lion Dingzhou Pagoda in Cangzhou and Zhaozhou Bridge in Zhengding Bodhisattva were found by Liang Sicheng in search of the pass-on of the local population. After Mr. Liang's analysis and publication of the bridge's history and construction technology, Zhaozhou Bridge became world famous immediately. Standing in front of Li Chun's bronze statue, we seem to have traversed the time tunnel and returned to the Sui Dynasty, witnessing the great craftsmen, leading skilled craftsmen to use their wisdom and sweat to complete this world's bridge history of many first-class boutiques. Several postcards of Zhaozhou Bridge were sent out, and they stepped out of the Guqiao Post Office at the gate of the scenic spot, thus ending their visit to the ancient bridge. On the way back to Beijing, driving through a rainbow-shaped arch bridge, I saw the shadow of Zhaozhou Bridge...
