Chinese man dresses as dead sister to help mother cope with daughter's death

In what can be called as the latest example of "filial piety" in China, a video about a man in his 50s taking care of his mother has gone viral on Chinese social media platforms.
According to the video, the man has been dressing as his dead sister for 20 years to help his mentally unstable mother cope with her daughter's death.
