Is it better to sell vegetables or flowers?

Well, I have a friend whose husband and wife run two flower shops. They are on the roadside near a residential area. This residential area is medium and there are many people nearby. At first, they were mainly relatives and friends buy buy. Later, I became familiar with the people on the edge of the community and opened a shop. Pass it on from friend to friend and buy it from friend. Or they may be the only flower shop nearby. They are close to five or six communities, and the price is relatively affordable. Although it is hard, it is very hard to buy food, and it earns more than buying food.
