Mrs Yu Youzhen

Owning 17 apartments and millions of yuan in the bank would mean an easy, leisurely life.

Not that she is busy adding to her property portfolio - she refuses to quit her day job as a street sweeper.But living a life of leisure is not for Mrs Yu Youzhen. The 53-year-old from Wuhan in China's Hubei province prefers the hard life.

The reason? She doesn't want to lose her work ethic and fears she may be a poor role model for her children, UK's The Telegraph reported.
