The ancient city gate is very vicissitudes in the old town. I walked around the old city with narrow roads, old houses, mixed people, and dense traffic (it feels very similar to the old city of Xiguan in Guangzhou, but the architectural pattern of the riding building is missing), and I can't tell the southeast and northwest at all. The Yuewen on the road signs seems to be the same. Pointing to Hoan Kiem Lake on the map (the gathering area of the old town hotel), asking passers-by, hiking to find the hotel.
