Hangzhou's economy is definitely good, so there is no need to compare it. But big cities also have their shortcomings. There are more people, and there are fewer opportunities. If you want to go to Hangzhou, I suggest visiting some places in the suburbs. If it is downtown, it is estimated that there is no chance. Although Yiwu is not as good as Hangzhou, it feels good to start a business, depending on what you have created. Yiwu seems to be a small commodity. I think the rest is free.
