Make money. The mahjong parlor itself is highly profitable. A mahjong machine charges 40 yuan for 12 hours a day. If there are four or five mahjong tables, it can earn about 200 yuan a day. Not to mention that the mahjong parlor is open all day and all night. The income from the mahjong table 24 hours a day is about 400, which is more than 10,000 a month. Although there are certain expenses for electricity and tea every day, about one hundred for a mahjong table is enough. It is enough for one person to manage a mahjong parlor, so his monthly income is about 10,000 yuan. Moreover, in a big city like Xi'an, the profits are higher.
