Actually that is the most powerful Mi Box in terms of HW specifications. It is called Mi Box 3 Enhanced (小米盒子3增强版 in Chinese), higher HW specifications than Mi Box S (international version, MDZ-22-AB) and Mi Box 4 (China version, MDZ-21-AA)

A few options for you.
1) Install app market like Dangbei/Shafa market and then install streaming apps and utilities apps to make use of the box, mainly for Chinese contents streaming but also okay for other possibilities
2) side load apps not requiring Google Play services by yourself, including phone version of Transocks or other China VPNs to utilise the bundled apps, or just forget about the bundled apps and install apps by yourself, for both CJK and English contents
3) If you are more tech savvy and more adventurous you can try root the box and load Google Play Services and Google apps, or even Android TV OS, then you can load other apps, including China VPNs from the Play Stores to utilise the bundled apps. For all kinds of streaming use cases. You can remove some of the bundled apps in this case.

But be careful since it may brick your box. YMMV.
