In order to obtain high profits, some KTV launched gray industries, provided invisible consumption and obtained improper income.
Often KTV will select a group of women with sweet looks and good voice conditions as employees in the store. But although they are ostensibly employees in the store, their wages are actually much higher than those of ordinary employees.
This is because some KTV bosses are disgusted with the slow arrival of money, so they have moved their minds and want to engage in a new type of "gray industry". Some KTV will provide special services behind customers' backs and beat the ball wildly.
