'Fire and ice' female goes viral

Zhang usually takes a quick shower after a day's coaching and hurries to the restaurant, taking care of the restaurant and serving as a restaurant singer.

Daytime diving and nighttime hotpot serving, just like a two-flavor-hotpot, gives Zhang a great sense of achievement.

"She is an ocean lover and a really good swimmer. She knows what she wants and is very easy to get along with," Tian Tao, Zhang's former coach, said.

"I feel lucky to do jobs that I both love. Having a hotpot after diving really makes my day," Zhang said.
