Chongqing Beibei State-owned 308 Factory; What's the full name?

The original name of Factory 308 is' Chongqing Huaguang Instrument Factory', which is correct.

It is right to call it' Chongqing Jialing Huaguang Optoelectronics Co., Ltd.'

I have never called the' Chongqing Beibei Huaguang Instrument Factory' mentioned on the second floor.

On the second floor, be modest if you don't know.
