Shangxiajiu has been the city’s main trading hub for over 1,500 years. The street has many contrasts between old and new – from its traditional Qilou-style buildings next to neon shop-fronts, to its Cantonese “dim sum” eateries beside international fast-food joints. Shop with the bargain-hunting locals along the arcades, near the glassed-in ruins of the old city wall.
