Hello, I am also in this business, but I do it in Guangzhou. Personally, I think this business also varies by region. It is best to do it in a place with relatively developed industry and commerce. To be realistic, It's easy to place an order this way. It is estimated that you should have done telephone sales in the early stage, and the probability of placing an order is very low. So as for the visit, I don’t know what kind of visit you will do. Is it a stranger’s visit, or is it the kind where you have been in contact and invited to visit? The most important thing in this business is to establish your own customer base, so that you can place orders while sitting in the office. As for building a customer base, you have to accumulate it slowly.
