Tik Tok's change can be used to buy coins and give gifts when the anchor broadcasts live. You can also buy dou+ to increase the exposure of your personal works. The unused change can be withdrawn into the bank card, and the money in the bank card can be used for other kinds of consumption.

If you have more questions, you can click the first three horizontal lines on my Tik Tok page, then click the wallet in the page, and click the FAQ at the bottom of the wallet page.
