There is usually a central station. Go to the Welfare Lottery Center and ask, we usually get 7% commission here in Jiangsu and 2.5% commission at the central station. Depending on the specific place, I can't say for sure. Anyway, that's what I said in Jiangsu.
And upstairs, don't talk nonsense if you don't know, because 2 yuan doesn't have a profit of 20 points, and it depends on the face value to get the commission!
