How much does it cost to have him become a live-in son-in-law for me?

He is an only child, employed at a tertiary hospital in the provincial capital, with a stable position, does not smoke or drink, and has almost no female friends in his social circle. He owns a car and plans to buy a house next year. Both of his parents receive over 7000 yuan in retirement pensions, and friends say he has a good temper.

After work, he cooks for himself, spends his private time at the gym or the library, and on holidays, he takes his camera out for hiking. What level does this make him among guys?

Afraid of pain and tired from taking care of children, he only wants to have one kid, and the child will have my surname.
