Relatively speaking, the sales of courses are relatively easy to do. China has a huge education market. Nowadays, most parents are willing to spend money on their children's education, and adults will also buy education courses for themselves in order to improve themselves after entering the society. Therefore, it is relatively easy to sell courses.

Sales courses can spread their own product information or brand through mutual communication between relatives and friends, or spread some attractive course information through the network to attract customers. It is a good way to sell courses and engage in some preferential activities.
