Another beautiful day. It is almost noon. It's unexpected that gong juren did not show up at the hospital. The conditions he needs to figure out are: 1) does gong jere not know about the zahar1 h variant, 2) is there virus sample and recovered patients, 3) can serum therapy, or neutralizing antibody, be applied, 4) has a vaccine have been developed, and 5) if there is one fugitive strain, one missed sequence, or leaked information, then can explain the rate of the formula pharmaceutical's vaccine development. He tells qiu that he and Zhang will be working extra overtime today. He says that it is better for them to supervise on the ventilators, since it will be hard for him to explain if it breaks down again. He teases that he will treat qiu fried chicken tonight and tomorrow's shares, and wonders if she looks like a "cheap woman" who can get "moved by fried chicken". He tells her that the test runs of the ventilator are almost done, and that it seems that they are about to "do something bad", but that there is nothing to worry about.
