Hello and welcome to Apple Support Communities, Leowill!
I understand you're studying in China, but your Apple ID is set to US, and you want to subscribe to Apple Music Student. I'd be happy to provide information on how to accomplish this.
You'll want to select the option indicating that you are studying abroad. Use the steps in this article: Get an Apple Music Student subscription
"On your iPhone, iPad, or iPod touch
- Open the Music app. If you don't see a "Welcome to Apple Music" message, tap For You at the bottom of the screen.
- If you're joining Apple Music for the first time or previously used a trial, tap the trial offer.
- If you currently subscribe to Apple Music, tap Sign In, then change to a Student subscription.
- Choose College Student or University Student.
- Tap Verify Eligibility. A browser window opens.
- Enter your academic (.edu) or personal email address and search for your institution's name. UNiDAYS might use this email to keep a record of your eligibility.
- If you already have a UNiDAYS account, tap "Already verified with UNiDAYS?" and sign in using the email address that you use with your UNiDAYS account.
- If you're studying abroad, first tap "Studying outside of [country name]?" and change the country or region.
- If you need help, tap UNiDAYS Support.
- Sign in to your institution's portal. In some countries and regions, you'll need to access the Apple Music offer while you're connected to your institution's Wi-Fi network or provide your academic email address. (Learn more about Apple Music availability.) After you sign in and are verified as a student, you'll see a message that says, "Open this page in 'Music'?" Tap Open to return to the Music app and finish the join process.
- If you're joining Apple Music for the first time, tap the trial offer. Otherwise, tap Start Student Membership.
- If prompted, authenticate your Apple ID. If you don't have an Apple ID, click Create Account.
- You might be asked to validate your billing info, but you won't be billed the full monthly price until after the trial ends. Add a valid payment method and tap Join.
- If prompted, agree to the terms and conditions.
- Choose genres and artists that you like. You can also see what your friends are listening to and get notifications when artists release new music."
