You can not flash another regional original gupdate.gcd into your 37xx., it may brick your gos, you need modified firmware.
From .exe file - You can rename it to .rar and then open , or right click then select extract file.
You will get gupdate.gcd inside, this file you need to make a modified firmware.

Your modified firmware will be
- original US boot.bin hwid 1101
- resources.bin from CHN
- fw_all.bin from CHN (overrided hwid to be 1101)

Merge all 3 parts by rgn_tool. Then flash into your 37xx.
