What is chemtrail? （什么是化学尾迹？）

I learned about this word 3 years ago and was surprised to see what it was on social media. It was done normally in everyday life. I’m sure you’ve seen this photo before. When I was a child, my teachers and parents taught me that it is a cloud that forms after an airplane passes, and that it is water such as filth from the toilet of an airplane. As a young child, I had no doubt it and set my mindset. I was ashamed to say that I had not questioned it for more than 50 years. There are a lot of lies on SNS, but there is also a lot of truth, and the final decision needs to collect information and make a judgment by yourself, but I feel that this chemtrail is true. Recently, I saw it here in Penang three times in one month. Since I just happen to see them only such numbers, but if I observe it 24 hours a day, 365 days a year, I can guess that a tremendous amount of chemtrails are sprayed. Chemtrails seem to be done by climate change companies, and they modify passenger and transport aircraft to load liquid tanks, and spray them from the sky. Governments know this and remain silent to their citizens. According to the analysis of the components of chemtrails by famous universities such as MIT, aluminum, barium, lead, arsenic, chromium, cadmium, selenium, etc. for artificial rainfall and climate change. For the human body, these substances are all poisons. Firstly, it is necessary to know this information. Not to change the subject but, it is not clear whether the coronavirus is artificially created or naturally created. China, U.S.A., and WHO do not seem to be willing to actively investigate. However, it is difficult to prove that it is naturally created, and Japan scientist recently has just published papers based on analysis results that are unlikely to be naturally created. What would happen to us if an artificial virus was put in the chemtrail and sprayed from the sky? In the war in Ukraine, there was a plan for the Ukrainian military to spray artificially created rabies virus in laboratory in Ukraine over Russia by drones, but the plan was derailed because the Russian army destroyed all laboratories in Ukraine. The sky and air are for all mankind. No one has the right to pollute clean air. How serious crime is it if those in power are spreading poison while ignoring it? I think the time has come for each of us to think about it seriously. How did you feel about chemtrails?
