I've searched for how to install Google Play on my Xiaomi 4 and it says search for 'google' on Xiaomi store. However, the only search result is Google Input Method for writing Chinese. The Google Service Framework by Eric Xiang is not there. Searching for 谷歌应用下载器 returns no results. I installed the Google Play APK on my phone but it crashes to desktop as soon as it's launched. I found the answer. Before I even finished writing my post. From this post an en.miui.com user Download Google services .zip here.
