A late childless couple in China donated five million yuan (US$735,000) to help 455 children with congenital heart disease, despite living an extremely frugal life themselves. The couple’s story was revealed at a charity exhibition late last month in Shanghai, according to the news website The Paper. Du Yingrong passed away in 2018 at the age of 81, while his wife, Lu Suying, died last year at the age of 92.
