Go to the front of Gao Qiao:
Take bus No.502 (about 8 stops) /80 1 Road (about 8 stops) /705 (about 15)/ 103 (about 16) at Kelin University to Gao Qiao Market West.
It is difficult to find Maojiaqiao in the hutong. I advise you not to go. You'd better go to Red Star Market, take bus No.7 at Kelin University and get off at Red Star Village.
Go to Mawangdui Market:
Take bus No.705 at Kelin University (about 22 stops) and get off at Mawangdui Market.
