Is there a commission for the glass in Zhengjiao Exchange?

There is a rebate. According to the regulations of Zhengshang Institute, the rate is calculated by hand, with one hand in 3 yuan, and each side receives one. But if you invest that day, its handling fee will be twice as cheap as that in Ping Ye. For example, when trading yesterday, both parties will receive commission, that is, 6 yuan will pay one opening and one leveling, while when trading that day, it will receive commission unilaterally, that is, 3 yuan will pay one opening (3 yuan) and one leveling (0 yuan).
