Tianmen people didn't lack nightlife, but most of them had to work hard during the day to earn money and support their families, so they had little energy to go out at night.
There were still plenty of wealthy idlers around, especially after the descendants of the Former Dynasty, the elites like Young Master Wang, collectively moved to Tianmen. In order to cater to the huge spending potential of these rich idlers, or perhaps to empty their pockets, the Tianmen City Government maintained a considerably tolerant and permissive attitude towards evening entertainment projects.
Apart from the three items that were banned, other aspects were loosely regulated.
According to the rules of Old Tianmen in the Jianghu World, markets operating before midnight were called night markets, and those after midnight were called ghost markets.
