Yu Jun is usually very busy at work. He is the earliest brother and sister to get married. Zhang's father and mother's first grandson is his son Weiwei, and the whole family likes it very much. Zhang's parents often go to defend David's activities in the Rain Garden.
There are few public photos of Yu Jun. I have only seen one, but personally, Yu Jun looks more like Yu Sheng than Yu Fei.
In short, whether they are happy or not is someone else's business, so we bless them.
