Visitors from Dongshan

Gu Yan, who has been charming and charming since she was a child, likes to drive cars and tinker with machinery, which are traditionally male tasks. When he grew up, he also chose to give up the easy and safe laboratory work and insisted on joining the hard and dangerous criminal police force.
