Weekend, the same can not go out, ****** (wrote can not be reviewed) attitude is still *** (write can not be reviewed), yesterday took advantage of the second time to do nucleic acid and bought a bit of food, the efficiency of secondary nucleic acid is still quite high, this time also serious, cotton swab turned several times, and requires us to issue an "ah" sound to increase the amount of oral saliva and lung qi samples, it seems that it is also combined with the frequent occurrence of multiple yin and yang situations during this time to do special optimization.
