When did the market system end? Did it end in the Song dynasty when time and space restrictions were broken?

The Tang Dynasty ended in the middle of the Tang Dynasty, but it was not explicitly abolished. The Tang poem, "Nowadays, it is not like the day of the ascension, but the songs and songs are still heard all through the morning", shows that if the curfew is isolated as in the early days, where is the red-hot night market.

While in the Song Dynasty, whether it is "Qingming Shanghe Tu" or Suzhou slate can be clearly seen, the city is divided into square table, but completely abolished the square wall and square door. Stores can be opened on the street

Tang in the middle and late people's spontaneous abandonment of the market, Song from the system completely abolished, Song Taizu had issued an edict "so that the night market in the capital, to the three drums shall not be prohibited since". Early market is to facilitate the management, the abolition of the late commercial circulation is the result of the time and space has nothing to do.
