To what extent is cleanliness addiction? The person who delivers food to him must wash his hair, take a bath and put on new clothes before delivering food to him. When the food is delivered to you, you must kneel on one knee and raise it to the height of your eyebrows, which is what the ancients called "Qi Mei".

Let the delivery man wash his hair, take a shower and change clothes, which can prevent dandruff, dander and microorganisms from falling into the rice bowl. Take Qi Mei as an example, this action is puzzling. It turned out that he held the rice dish high for fear that the spittle of the delivery man would pollute the food. You know, spitting can spread diseases. If the delivery person suffers from influenza, mumps or severe acute respiratory syndrome, he may be infected to Ni Yunlin. Therefore, it is scientific for Ni Yunlin to ask the delivery staff to take Qi Mei as an example.

We China people have always neglected food hygiene. Since the Five Dynasties, the * * * rice system has prevailed. During the dinner, a large number of people sat around the table, chopsticks were so anxious that * * * swept away seven dishes and eight bowls, and * * * shared saliva with each other. Ni Yunlin not only didn't eat with others, but also didn't drink with others. He even thought about preventing the delivery man from drooling. It's really early. His health awareness is much stronger than that of other ancient people.

Ni Yunlin is also very particular about drinking water. He likes drinking spring water and hired a porter to pick mountain spring water every day. The road is long and the burden is heavy, but Ni Yunlin is not allowed to carry porters to change shoulders. When the spring comes home, Ni Yunlin only drinks the bucket in front and the bucket in the back is used to wash his feet. He thinks the water in the back bucket smells like a porter's fart. One day, Ni Yunlin cooked porridge with the bucket of water in front of him and tasted a strange smell. He called the porter and asked, "Why did you change your shoulders on the way?" The porter said, "dear sir, I dare not change my shoulders." "liar! If you don't change your shoulders, how can the bucket of water in front smell like fart? " "My Lord, the little boy turned when he took the door, and the order of the buckets changed. You must have put the back bucket in the current bucket. "

Teacher Ni Yunlin may not know that farts dissolve in water to form hydrogen sulfide water. It is beneficial to drink low-content hydrogen sulfide water for a long time. It can promote gastrointestinal peristalsis, prevent constipation and eliminate phlegm. It is said to be effective for chronic bronchitis. Therefore, Teacher Ni's correct approach should be to encourage porters to change their shoulders frequently and fart more. I guess Ni Yunlin won't do this, because he has a cleanliness addiction, and cleanliness addiction and health preservation are sometimes incompatible.
