1. Because the production pace of Tianjin Wangwenzhuang Beverage Factory is very fast, the staff need high-intensity labor to meet the production demand, so they are tired.
2. Tianjin Wangwenzhuang Beverage Factory is closed and lacks fresh air, so I feel very tired.
The working hours of the beverage factory have exceeded eight hours every day, and there are still two hours of overtime. To sum up, it is still very tiring in Tianjin Wangwenzhuang Beverage Factory.
