Hi, Almend. FUMIN COMMERCIAL STREET is not in Humen, but in Nancheng District. It is a walking street with many fashion stores.
In Humen, there are some wholesale markets like Fumin fashion city, Fumin internation commoodity and trade city, Fumin shoes and learherwear city. Are you looking for these wholesale markets? Bus L1 goes to these places, but you'd better go there with a Chinese friend because the bus driver can speak Chinese only.
