Wuzhou's arcade streets, where the iron flood-rings still hang on the columns

The first thing at eye level on Dadong Road (大东路, Dàdōng Lù) is not a shop sign but an iron ring, rusted the colour of old blood, bolted into an arcade column at about the height of a grown man's shoulder. It is a mooring ring. When the Xijiang (西江, Xījiāng) comes up in the summer, boats are tied here, to these same columns, and the family upstairs carries the rice and the television to the second floor and waits for the river to decide how long it intends to stay.

A city built to be flooded

Wuzhou (梧州, Wúzhōu) sits at the eastern edge of Guangxi, hard against the Guangdong border, where the Gui and Xun rivers meet to become the Xijiang. For most of its history the water has run the town rather than the other way round, and the town has stopped arguing about it. After fire cleared the old wooden quarter in the 1920s, the merchants rebuilt in the southern qilou (骑楼, qílóu) style — a continuous shop-house arcade where the upper storey oversails the pavement on columns, so you can walk close to a kilometre through the old town without once leaving the shade or the rain. More than five hundred of these buildings still stand around Dadong, Datong and Wufang (五坊路) roads, and the district calls itself, without much modesty, Qilou City (骑楼城, qílóu chéng).

Read the columns and you read the floods. Painted lines and small enamel plaques mark the crests of the famous years — the great water of 1994 sits above the doorways, and higher marks climb toward the first-floor windows. Look up and you find the reason those windows are doors: many arcade houses have a second entrance on the upper floor, a 水门 (shuǐmén), a flood gate reached only by boat when the street below has become a canal. The rings come in threes on some columns, one low, one a metre up, one higher still, so a boatman could always find one at the surface whatever the river was doing that week.

The tea that went downriver

Wuzhou is the home of Liubao tea (六堡茶, Liùbǎo chá), a dark fermented tea from the hills of Liubao town in Cangwu (苍梧, Cāngwú) county, an hour north. It is not a tourist souvenir here; it is what the town drinks. For a century it went the other way — packed into baskets and floated down the Xijiang on what the older residents call the 茶船古道 (cháchuán gǔdào), the tea-boat road, to the tin miners of Malaysia and Singapore, who trusted its warmth against the damp of the mines. Ask for the aged leaf and you are handed something closer to soil than to green tea, with the faint sweetness the sellers call 槟榔香 (bīnglang xiāng), the betel-nut note.

The family teahouses are set back from the arcades, up a stair or behind a herbal-medicine counter, six or eight tables and a wall of stacked baskets. A pot of two- or three-year leaf runs around 30 to 50 yuan and is refilled until you stop; a pressed cake of properly aged tea can climb past 300. Nobody hurries you, and the pours keep coming as long as you tap two bent knuckles on the table to say thank you. One shophouse on Jinzhong Road has been run by the same family for three generations, the granddaughter now weighing leaf on the same brass balance her grandfather used, her father's calligraphy for the tea names still hanging, ink gone brown, above the till.

Breakfast under the arcades

The Wuzhou breakfast is a defence against the humidity as much as a meal. Bingquan soy milk (冰泉豆浆, Bīngquán dòujiāng) is the institution — made with water from the Bingquan spring on the edge of town, whipped until a collar of foam rises over the rim of the bowl, sweet or savoury, about 8 to 12 yuan with a fried dough stick. It is thick enough that the first mouthful is more like eating than drinking. Down the same block you will find turtle jelly (龟苓膏, guīlínggāo), a bittersweet black herbal set that Wuzhou has made and tinned for over a century; a bowl with a thread of honey costs a few yuan and is taken as much for the heat of the day as for the taste.

If you sit down for lunch, the dish to order is paper-wrapped chicken (纸包鸡, zhǐbāo jī) — pieces marinated, folded into squares of cellophane paper, and fried so the parcel holds every drop of the juice until you tear it open at the table. It is a Wuzhou dish, not a national one, and it tastes like it has never left home.

Where two rivers keep their colours

Walk the qilou grid to its river edge, near Dahe Bridge, and you reach the confluence the locals call 鸳鸯江 (Yuānyāng Jiāng), the mandarin-duck river — the clear green of the Gui running alongside the silt-brown of the Xun for a long stretch before the two finally give up and mix. On a still morning the seam between the colours is a line you could photograph, and the small ferries and sand barges cross it as if it were not there.

在梧州，河水从不客气，而这座城早已学会与它相处。

Some of the arcade houses now take guests, a room or two above the shop, and staying in one is the point rather than a compromise. The floors slope where the timber has settled, the shutters are the original louvred wood, and from the upper window you look straight into the underside of the arcade opposite, close enough to hear the tea being poured across the lane. A double room runs roughly 150 to 250 yuan, less than a chain hotel by the station and worth every difference.

Getting there, and when

Wuzhou is on the Nanning–Guangzhou high-speed line, which makes it far easier to reach than its obscurity suggests. Trains from Guangzhou South (广州南) reach Wuzhou South Station (梧州南站) in about 90 minutes for roughly 80 to 110 yuan in second class; from Nanning it is a little over two hours. The catch is the station itself — it sits well outside the old town, and there is no metro, so budget a 30- to 40-yuan taxi or the airport-style shuttle bus into the arcades, and do not stand at the rank expecting the fare to be short. Come in the dry cool of late autumn through spring; the arcades are at their best then, and you avoid the June-to-August flood season, when the romance of those iron rings stops being theoretical. The one mistake worth naming: treating Qilou City as a two-hour photo stop between other places. Its pleasures — the tea that will not be rushed, the foam on the soy milk, the seam in the river — are all things that reward a slow morning, and give nothing to a schedule.
