Long-distance transport in China is good, but local transport is less efficient, except for cities with metro systems. The choice of local transport is diverse but vehicles can be slow and overburdened, and the network confusing for visitors. Hiring a car is often impractical, while hiring a bike can be inadequate. Unless the town is small, walking is often too tiring. On the plus side, local transport is cheap, taxis are usually ubiquitous and affordable, and metro systems continue to rapidly expand in large tourist towns.
