I once attended an exhibition, in which there was a company's exhibition mode, and the key was how to attract many customers:

Their product-fingerprint lock

They made a transparent box containing 100 yuan in cash. Put their fingerprint lock on this box. They said that whoever can open this fingerprint lock will have all the money inside. (of course, you can't smash the box, at least. )

Tell others that the opening ceremony is very important, but they are all friends invited by themselves with invitations, which is a bit too limited. If we can use this method like fingerprint lock, it will attract more customers and be very helpful for future business. Most people should pay great attention to a good start.

It depends on what products the landlord has ~ ~
