All the methods that can bring enterprises to talk about capital can be used, such as investment promotion activities, exhibitions, intermediaries, networks, advertisements and so on. But according to my personal experience for many years, not all methods will be effective, and sometimes I can't even see a shadow after spending money. We should carefully evaluate it according to the actual situation. If I don't have a special understanding of this aspect, I recommend a book: Practical Guide to Investment Promotion in Industrial Parks, which is the only book in the industrial real estate industry that systematically introduces and guides investment promotion.
