What about the cleaning agent of Huayang Ensai Co., Ltd.?

As for cleaning agents, the sales staff inside them always say that you will know what it means if you get 7 points for sales and 3 points for technology. The technology of their products is not very high and the technology is not good, but they have good sales methods. In fact, they still do the things commonly used in ordinary sales, or invite people to dinner to contact their feelings.
