The core issue is YinXiang uses different name schema, So the EN database can't be recognized.
You can get out of the trouble to follow below steps:
1. Switch off the internet access
2. Find the location of database files. Generally, it lies in "C:\Users\your username\Yinxiang Biji\Databases" with ".exb" as suffix.
3. Replace the "robin_rhu#app.yinxiang.com.exb" with the EN one.
4. Open YinXiang desktop, Now, all the notes appear again. Export all notes as a ".enex" file.
5. Import the generated ".enex" file and move the unsynchronized files into the correct directory one by one.
