1, I don't know how many years you have been working as an elevator, but from your question, you should have just entered this industry. Master professional knowledge.
As a newcomer in this industry, I suggest you learn more from the old employees of the company and rely on how they visit customers. This is your focus now.
3. Your work mainly focuses on project bidding. You have no experience in doing this, and you need 1-2 years of accumulation.
4. In the customer base, you can think about who will contact your products, peers, design institutes, real estate companies, elevator agents, elevator builders and so on. All these require you to communicate and visit.
I hope it helps you!
