I agree 100% with Colin.
Early on in the outbreak I started wearing a mask, when many in my xiaoqu had not started yet. I was asked by one of my English speaking neighbors, why. My answer was simple. Although the risk of infection was low, if anyone in the xiaoqu had got sick, I believed that they would be looking for people to blame. The fingers would point at the outsider who was not wearing a mask.
Personally, I would not power wash a bike of any kind. The jets are powerful enough to wash the grease out of bearings, and chain links, especially if the jet wash uses any kind of detergent. Water can also get into electrical components, especially if the machine is a few years old.
If you want a low pressure job, then go to a low pressure culture. I know teachers in Laos who say the teaching environment and people are wonderful.
Education in China is a pressure cooker. I know teachers in Kindergarten who have been criticized because parents 'don't pay the school to let them play'. There are many aspirational parents in in rural areas, who want children to succeed/exceed.
Unless you get into remote rural, perhaps teaching ethnic minorities, you won't find any kind of rural idyll. Even if you do, as @Janjal said, schools won't have a budget, or even need for a native English speaking teacher.
