Let me share with you the places where I often buy books. I often go to Wangsiying Book Market, where there are many very large books. I buy a lot of books every time I go, and sometimes I buy them online if I don't want to move. I prefer Jiahu Book Wholesale Network, which is a place where I buy books online. Books are very cheap. Recently, I bought a lot of picture books for my children, and I can reach the wholesale price standard of members after buying them several times.
