Liu, who was born in Chongqing's Jiangjin district in 1993, showed keen interest in painting as a child. She said she taught herself to crochet using online tutorials in 2019, when she was pregnant and eager to find ways to kill time.
"Crocheting is easy, but shaping is hard," she said, adding that her early works failed. She came up with the idea of making potted flowers. To make her creations vivid, she brought real flowers home and observed them closely.
