One of Sheng's most impressive experiences was seeing 146 patients from 7:45 am to 9:45 pm. "It happened when I was in my 50s. I ate nothing that day, only had some milk," she said.

Though awarded the "lifelong achievement physician in pediatrics" at the 24th Congress of Chinese Pediatric Society in this October, Sheng seems not proud at all. "It's only a piece of paper to me."

"She is seldom home to accompany me or our kids because she is always busy, even now. But I understand her. Saving lives is a good deed, I'm glad she helps kids free from asthma," said Jin Jiajun, Sheng's husband.

Sheng is also a wanghong, or "internet famous". She spreads the knowledge about pediatric asthma via livestreaming videos in her spare time. "I receive 100 people at most in the hospital, and I can only teach them basics. But tens of thousands of people watch my channel online, and I can also answer their queries, which is more convenient and efficient."
