The first aspect is to choose to sell sporting goods: because the landlord is a physical education teacher, selling sporting goods should be handy, and you can use your own advantages to show the superiority of goods, such as selling basketball, such as selling sports T-shirts.
In the second case, the landlord is a physical education teacher and must be good at teaching students running exercises and equipment. Therefore, the landlord can sell related sports equipment, such as selling parallel bars, horizontal bars or wristbands. And the landlord can show it to students or potential users who want to buy it outdoors, and they may also buy it for the landlord.
Third, the landlord can open a gym: because the landlord is from sports, he must have some experience in fitness and physical exercise, so it may be a very good choice for the landlord to open a gym. Of course, the premise of the gym is to see a small gym or a small yoga studio first, which will gradually develop and sometimes open a bigger one!
