Thank you. I used this number as my ID by accident and just keep

since I don't know how to change it. It is my ID, not Mia Jia.

We do not hit him. I read the book about education and it said it is wrong to punish hitting by hitting. Because the kid will be confused if you asked him not hitting, but you hit youself. But sometimes I really want to spank him to try if it works.
