Homesick poems. For Xi Murong, nostalgia is like a tree without annual rings. To Yu Guangzhong, it is a small stamp. For Zhang Lei on Good Voice, it is a song called Nan Shan Nan. Why does Duoduo write about flowers and clouds? Because both flowers and clouds can be combined with the word "duo" to form a word, "flowers and clouds". So there are two flowers. The meaning of writing is that Duoduo misses home.
