The best thing to see on this street is not a building but a transaction. The goods on Dihua Street are stock, not display, and a good share of the customers are not travellers.
Three strands of market
It helps to read Dadaocheng’s market layer in three strands. First, the herbal medicine and dried-goods wholesalers that fill Dihua Street Fact. Second, the fabric and textile trade of Yongle Market beside the City God temple, which serves people who sew Fact. Third, the Lunar New Year goods street, when the whole road becomes a vast market before the holiday Fact.
The condition of still working
What matters is that none of the three is a re-enactment. They still wholesale, and the customers include cooks and herbalists buying stock Fact. This condition is what separates Dadaocheng from an embalmed old town — what you see here is not a preserved scene but a continuing one Estimate.
Should you buy?
Looking is fine, but many shops will sell small amounts Estimate. Dried shiitake, jujube, cinnamon and dried seafood are more practical than most souvenirs. In shops whose main business is wholesale, though, it is courteous to avoid the busiest hours.
Day and season
The day matters here too. Many shops close Monday, so Friday or Saturday is safer Fact. Timing your visit to the Lunar New Year market changes the density of the street completely, but it follows the lunar calendar and the Gregorian date shifts annually Unconfirmed. If you want a quiet street, avoid that season instead.
