Sun Yongfeng's family from Zhongshan won the title of "National Five-Virtue Family" at the 12th National Five-Virtue Family Video Commendation  Conference held on December 31, 2020.

Sun Yongfeng, 65, a retired hydraulic engineer, is an avid collector of ancient books. He has collected more than 30,000 books over the past decade.

In order to encourage more young people to get into the habit of reading, Sun Yongfeng and his wife have spent about one million yuan they had saved in their lifetime on building a public welfare book house. "Wanjuan Tower", which is located in Gangkou Town, was completed in 2015. Since its opening six years ago, the book house has attracted more than 10,000 readers to come for various reading and related activities.
