Why did Tongnan Oupengba stop transmitting sound?

The reasons for the suspension of sound transmission in Tongnan Oupengba are as follows:

Tongnan Oupeng Bachuan Silver 1 suffered an epidemic before, which affected the normal operation of the production process and led to local shutdown.

2. Strong exchange rate change is also the main reason, and the corresponding increase in raw material prices makes it impossible for the company to maintain its original operating conditions, which also leads to local shutdown.
