Introduction to Taiyi District: Taixi - the descendant of Shaohao of the Jintian clan and the grandson of Huigong is the "third generation ancestor of the surname Zhang". More than 5,000 years ago, he "xuanfen, Tao, and Daze were protected by the Great Plains." He controlled floods in the Fen River, and the floods receded to reveal the "Great (tai) Plains", which is today's Taiyuan Basin, so he was honored as "Dragon City" Ancestor". He was a hero of flood control hundreds of years before Dayu. He was truly the "first person to control floods in China" and was named the "God of Fenshui". According to legend, he subdued the black dragon entrenched in the Fen River, fearing that it would fake his death, and stood here to guard it. Over time, he transformed into Taiyi Mountain.
