You don’t need a computer to open a Douyin store, because it is easy to operate on a mobile phone now. A computer is just the icing on the cake, not a must. But you have to think about it. Choose the most popular industry to increase your economic income. It will be more difficult to open an unpopular industry. So you can open a store with a mobile phone, no need for a computer. I hope you can make a lot of money.
