Second, go to the third-and fourth-tier market areas to see who is doing better, and then talk to him about Haier's agency. It's slow, but you know your customers like the back of your hand.

Third, do both. The above two methods are carried out together.

Supplement: the first one can gather interested people in one place and then conduct conference marketing, which will be better!
