It took my a long time to find a solution, none of the solution I have tried many solution on the internet but none of that is working. So I decided to write one to save someone time for someday 
Symptom:
1. Displaying "Unknown Issue with Google Play Services" on the notification area for a app. Any apps relied on Google Services like Google Map, Play Store, or even some game like Pokemon Go is not working.
2. When go to settings of selecting Google Account, it force closed. So you can't remove or add Google account / change the sync settings anymore.
Root Cause:
Still unknown, may be due to some bug in Mi 5s offical firmware issue. Even I have clean install of offical global rom but still having this issue after 2 -3 days of use. I dont have such issue when using another phone before but just having this issue when using Mi 5s. (I am purchased two Mi 5s and both are having the same issue)
Solution:
0. Root privilege is required, there are many thread already teaching you how to root Mi 5s so I won't go through the details of rooting Mi 5s here
1. Download Google Play services 9.8.77 (448-135396225) apk and put in the internal storage
(Due to some restriction in xda, I can't post the apk links or upload to this thread, please search in link on the internet, the MD5 for this apk is 1B552C81376A29E8F1F4B2ED9F990B11)
2. Delete Google Play Service
Since Google Play Service is come with the ROM and it is "system app", root privilege it required to remove a system app, to remove a system app, you can search "system app remover" on play store, there are many application which help you to remove system app with one click. For me, I am using a paidware called Titanium Backup so I dont have any recommendation with the above free system remover, but I think most of them should work.
After you have deleted Google Play Service, a pop up about "com.google.gms has stopped" will keep popping continuously even you click "cancel" everytime, but don't panic! Now just hold your power button and Reboot the device
3. Install Google Play Service
After rebooting the device, the "com.google.gms has stopped" pop up will still keep popping continuously. When you click "cancel", there is a 1 second small time gap before the next pop up come in, so make use of the time gap to locate the Google Play Service you have downloaded on the internal storage and install it.
4. Add Google account
After the installation, the pop up will be gone. However, all of the Google account which has configuration on this device are also gone, so you need to add it back as usual.
That's it. Try to open Google Map now
