When watching Huawei music programs, you can differentiate between paid and free programs by the following methods: 1. Check the program guide: You can check the program guide before watching the program to see if the program needs to be paid. Some programs might be marked on the page as "requires payment to watch" or "limited viewing but certain content requires payment." 2. Check your information: Some programs may require you to be a member of the Huawei Music Service. You can check the information on the "Submit" page of the Huawei Music APP to see if you have already submitted to the program or if you need to re-submit. 3. Check the advertisement bar: Free programs usually have advertisements, but paid programs don't show advertisements. If the full version of the program could be seen, then the program was limited to free viewing; if the full version of the program required payment, then the program was charged. It should be noted that the above method may not be applicable to all programs and all situations. The specific distinction method may need to be operated according to the actual situation.
