Introduction to Zhuoma Lake: Only ten meters away from the Jiangnan Pavilion, there is a pool of clear water, several meters deep and crystal clear to the bottom. This rectangular stone pool is more than ten meters long and about five meters wide. The east end turns to the south. The three characters "Zhuomatan" are engraved on the stone wall. According to legend, Zhong Lichun, the wife of King Xuan of Qi during the Warring States Period, visited Laolong Bay and washed war horses in Triangle Bay, hence the name "Zhuo Ma Tan". The water in Zhuomatan Pool is clear, but the water has a large proportion. People tried to throw coins into it, but it floated and took a long time to sink to the bottom. The pool is in an irregular "S" shape with several turns. Therefore, it is also known as "Bajiao Bay".
