Tell me about Xiaoshitang.

A: Example: Sentence: Don't move; I was in the distance, and the contact was sudden.

Reason: these words describe swimming fish, and the combination of dynamic and static fully shows the interest of swimming fish; It also indirectly shows the clarity of Xiaoshitan water.

The third paragraph discusses the water source and pool water scenery of Xiaoshitang. "Look at the southwest of the pool, you can see the flicker. Their shore potentials are different from each other and their sources are unknown. " Looking to the southwest, a stream twists and turns, like the Big Dipper, like a snake. Some places are bright and some places are dark. The banks of the stream are strewn at random, scrawny and with jagged teeth. Here, the author successfully uses metaphor to describe the shape of the stream with the twists and turns of the Big Dipper and the crawling of snakes, and to describe the banks of the stream with the teeth of dogs, which makes us feel lifelike. "I don't know its source" gives readers a feeling of confusion.
