How to do unannounced visits, in fact, each company has different requirements, but for part-time people like us, it is just convenient. I have done analogies such as catering and clothing before, and household appliances have not been challenged, but they are definitely similar.
For the company ... I come from Shenzhen. Personally, I prefer the information consultation in the study room in Shenzhen. The manual they gave me was clearly written, and someone was carrying it. When I first joined the business, I was a part-time job in this family. Personally, I feel much better than other personal or intermediary things I have done.
