A set of pictures of Lei Jiayin's stills - the human world - is shared with everyone. Zhou Bingkun is played by actor Lei Jiayin, the third child in the Zhou family and the youngest among his brothers and sisters.Tough and brave, he is a down-to-earth grassroots worker. He does not have Zhou Bingyi's great ideals, nor does he have Zhou Rong's free and easy attitude. He can only stick to his heart and work conscientiously.
