The landlord's idea is very good. It is generally profitable to open a tea shop near the school. It is best to join a tea shop to open a tea shop, which can save a lot of trouble. Just make a simple metaphor, such as a teacup and a sealing film. If you make it yourself, you should print your own logo on the cup and sealing film! If you go to the factory to make sealing films and cups, people won't make them for you. If you make them into hundreds of thousands, it is estimated that it will take several years to use them up. After a long time, they will go bad and can't be used at all. You have to find a place to pile them up. There are many other inconveniences.
In fact, some people don't charge the joining fee, and some people charge tens of thousands or hundreds of thousands of deposits. It depends mainly on your choice. I recommend "Green Dream Milk Tea Join". They do a good job, without any joining fee, with little investment, low risk and high return.
