Why might a new business not be successful?

One major reason a new business might fail is not understanding the local market well enough. For example, when my uncle opened his Hangzhou restaurant in Shanghai, he initially struggled because he didn't realize how different the tastes were compared to his hometown. He had to adjust some recipes to suit Shanghai customers' preferences while keeping the authentic Hangzhou flavors. Another common issue is poor financial planning - many small businesses underestimate their operating costs. I've seen cafes in my neighborhood close within months because they didn't account for how expensive rent and ingredients are in Shanghai. Even with a good product, if you can't manage the numbers properly, it's hard to survive.
