Li Cangxin, a graduate student of MIPAV lab class of 2023, is from Changyuan, Henan Province. Because of Dai Wangshu's "Long and Lonely Rainy Lane", I came from the rough Yellow River to the soft Jiangnan. "Rain is the fault of a lifetime, rain is the sadness and joy of separation", I am glad to learn and progress together with you.
