Professional knowledge related to property management

Good interpersonal skills, strong communication skills, knowledge of architectural knowledge and foreign languages (may meet foreign owners). Ha ha. I have done it before, but I just graduated at that time. When I apply, the other party may think that my major has something to do with the house. I passed without asking anything. Later, I learned a lot of knowledge and wanted to change companies. At that time, when I applied for a job, the other party asked me a lot of professional knowledge, such as waterproofing of exterior walls and bathrooms, anti-alkali phenomenon of walls, cracks, etc. What should I do if I can't receive the property fee? Ha ha!

But the property management salary is too little. This suggestion is too much.
