The query method for missing translations of QQ Music is as follows:

1. Check whether the network connection is normal. An unstable network connection will cause the translation to fail to load.

2. Update QQ Music to the latest version. If you are using an old version of QQ Music, the translation will not be displayed properly.

3. Log in to the QQ Music account again. Sometimes the login status is invalid and the translation cannot be displayed properly.

4. Try to open QQ Music on other devices or browsers. If the translation can be displayed normally on other devices or browsers, it means there is a problem with the device or browser you are currently using.
