It's good. I need to feed a batch of materials for my work. Consider it 3 tons. Throwing 2 tons manually. 500kg gas crane, and almost 20 small bags, one at a time. Drink plenty of water before feeding, because you will sweat after feeding. Sweating can detoxify! Young people should suffer. Then the plc control system cannot match the automation. Switch valves and run upstairs and downstairs. Some automatic valves need to be opened manually, so you can get used to it if you have nothing to do, and you can get used to it if you open it. You can also exercise muscles! The sampling was hung with a teacup tied with a chain. Be careful of falling. Toluene recovery is poured with a spoon. Dissolved salt should be put into 30 bags. Take your time. No one is competing with you for a class, just two people. There is another person's. Just finished feeding, ready to have a rest. The next process will keep you busy again. When you find that time is not enough. Sorry, it's time to get off work. Let's leave now. We are a formal enterprise. Get off work on time
