Introduction to Lancuiting: According to legend, when Ye Fashan, the Taoist master of the Tang Dynasty, was traveling around, he once passed by the Ruoliao Valley and found that the Ruoliao Valley was rich in yin-yang and eight trigrams, so he carefully selected a flat round A pavilion is built in the shape of a basin for resting and enjoying the scenery. When the craftsmen finished building the pavilion, the Heavenly Master wrote down the three words "Lancui Pavilion" and chose the auspicious day of the zodiac to hang the pavilion. Unexpectedly, the mountain god of Ruoliao Valley quietly brushed away the handle on the left side of the word "Lancui". When the craftsmen hung up the plaque and lifted the red cloth, they discovered that "Lancui Pavilion" had become "Lancui Pavilion". Tianshi suddenly realized: It turns out that the scenery of Ruoliao Valley can only be viewed, not taken away. (Note: The original pavilion has been destroyed, and the current pavilion was rebuilt by later generations in memory of the Taoist heavenly master Ye Fashan).
