关系户 A relationship household. A unit or person that gains benefits or convenience through special connections.
一人得道，鸡犬升天 When one man attains the Way, even his chickens and dogs rise to heaven. When one person gains power, everyone connected with him rises too. Said with irony. The image comes from the Han dynasty Lunheng, which tells of a king whose whole household rose to heaven with him, so that dogs barked in the sky and chickens crowed in the clouds.
