Yesterday, I sent a batch of medical power supply to several hospitals. After a busy morning, I finally delivered all the goods. Today, a colleague came with me to deliver the goods. It was a waste of time and a lot of effort for me to move up and down the medical power supply. I went to one of the hospitals and got some staff to carry the medical power supply with us. They said that we had sent it just in time for their hospital to be in urgent need, so it was mutually beneficial to help us unload it so that we could leave early and they could use it as soon as possible. Now I have been trained every day for my muscles, and I am not tired of moving things.
