If you have a subscription to Disney plus, there is a rich trove of resources for learning Chinese. Any Disney (including Pixar, Marvel, etc) film that has been ever released in China or Taiwan can be found with Chinese audios and subtitles on Disney Plus.
Disney offers 2 or 3 options for Chinese audio, depending on the show.
For Audio:
Chinese (中文) – Mandarin (Taiwan accent)
Chinese (普通话) – Mandarin (China accent)
Chinese (粤語) – Cantonese (Do not select this one. Cantonese is very different from Mandarin…)
For Subtitles:
Chinese (简体) means simplified Chinese. Both Chinese (粤語) and Chinese (繁體) are traditional Chinese.
