Wudaokou clothing market is located in the northeast corner under Ponte dell'Accademia in the North Fourth Ring Road.
If it's Qianmen, you can take the subway and change to the subway, get off at Wudaokou and go south.
You can always see Ponte dell'Accademia, but there are also many very personalized clothing stores in Wudaokou Station of the subway. I believe that the landlord will not want to go to Wudaokou Clothing City after visiting those small shops ~ ~ ~
