I suggest you work hard and think hard in the past, don't limit yourself to the investigation of hidden dangers on the spot, learn to find the root of the problem and put forward solutions to the problem from the source. At the same time, we should communicate with department leaders and colleagues, ask questions if you don't understand, and be good at summing up experiences and lessons. Read more books in your spare time and learn English well. There will be many opportunities in the future.
