How easy is it to start a successful business?

I'd say starting a successful business is quite challenging these days, especially in competitive markets like Shanghai. The main reason is that you need both a solid business model and the ability to stand out from existing competitors. For example, as a UI designer, I've seen many tech startups fail because they had good ideas but couldn't differentiate their products enough. That said, with platforms like WeChat Mini Programs, it's become easier to test ideas with lower initial costs compared to traditional brick-and-mortar businesses. The real challenge comes when you try to scale up sustainably.
