Zhang Shou-shan, the retired founder of Yuanshan Group, disguised himself as a rural old farmer to test family affection and went to the city to visit a grandson he had never met. Instead, he was despised by his daughter-in-law and parents-in-law in every possible way, driven to live in a utility room and eat leftover food. Only his little grandson treated him sincerely, and his cowardly son even drove him away in order to cozy up to group cooperation. Unable to bear it any longer, Zhang Shou-shan directly called a halt to the project. His identity as chairman was exposed, the family came to their senses, and finally the whole family was reunited.
