1. Open the Tik Tok APP and click "I" in the lower right corner.

2. On my homepage, click "Edit Profile" in the middle to edit my profile.

3. In the pop-up window for editing data pairs, find "Profile" and click it to edit your profile.

4. At this time, a window to modify the configuration file will pop up. Under the profile, just enter your own micro signal. However, it is worth noting that "personal micro-signal is: XXX" cannot be written directly, and it needs to be changed. It can be written as: WX: XXX, so that Tik Tok officials will not refuse to give it to you, otherwise it will not be submitted.

5. After modification, click the "Save" button in the upper right corner.
