We’ll, there are two possible ways to fix that problem. Somehow import women to China. That’s not very feasible. Or you can simply reduce the number of men by starting a bloody war - like maybe invading Taiwan.
Taiwan will fall in a few hours. Not bloody enough.
There are also only 2-3 million Taiwanese women in the 18-35 age bracket, assuming you slaughter all their men.
