预防针： （1）专业外行，很少使用专业术语或引用专家观点； （2）凭直觉写的文章需要凭直觉来看； （3）内行读者，建议摘下专业眼镜，裸👀看更好。 Reader Vaccination: (1) The author is a professional layman, rarely using professional terms or citing expert opinions; (2) Articles written by intuition need to be read intuitively; (3) For experts, it is recommended to take off professional glasses and read with naked eyes.
My own measures against the COV.
* Full mask when entering a crowd.
进入人群时完全戴口罩。
* Increase the indoor humidity & ventilation appropriately if the
lungs are infected.
如果肺部感染，适当增加室内湿度和通风。
* Keep the spine straight to clear the bottom-up waterway.
保持脊柱笔直以通畅自下而上的水道。
- Not a suggestion to others.
