Wuzhen sits in the flat, waterlogged country north of Hangzhou and is promoted, accurately, as China's last household pillowed on water. Four old streets cross in the shape of the character for ten, and the canals, streets and lanes stack up in a grid two deep — water beside land, a house at every step. It is a small town that has been made to look exactly like itself, only more so.
The town comes in two halves and they are not interchangeable. The East Scenic Zone is the older, dingier, more human one: the workshops, the dye yards, the ancestral halls, the house where Mao Dun was born. The West Scenic Zone is bigger, deliberately prettier and more commercial — a dozen islands you reach by ferry, restaurants and bars, and, after dark, the thing everyone comes for, the whole quarter lit and doubled in the water.
What you actually want here is not a checklist of sights but the right two hours. At dawn the canals blur into mist and locals wash vegetables at the water steps; at dusk the day-trippers drain out about 17:00 and the town goes quiet, then lights up. Sleep inside and you get both; come as a day trip and you get neither.
It is also one of the easiest water towns to reach — an hour from Hangzhou by road, 30 minutes from Shanghai by rail to Tongxiang and then a bus. Two days is the natural length: one for the East Zone's old lanes and workshops, one for the West Zone's gardens and its night.
