By now, most people would have seen this video produced by MCYS to promote the family value of filial piety. Despite how the mother treated the son and his family when she was old, the son remained filial to the mother even though the others ostracized her. He would always remember how she rushed him to the hospital when he was young, very sick and begged the doctors and nurses to treat him.
She never gave up on him and so he never gave up on her even at her deathbed. Of course, the short clip was accompanied by the famous hokkien jingle 天黑黑 which made the whole thing so endearing.
