Why do surveying and mapping people want to switch to the internal industry? Aren’t the wages in the outside industry high?

How should I put it? Anyway, it is true that the field work is more tiring. I am away from home for a long time and there is no vacation. However, the salary is high, about 8,000 a month now. After tax, it is almost pure salary, but it is not conducive to Home construction and field work are not highly technical jobs. You can learn it in just one day if you work hard! I go back to the company and work in the office from 9 to 5, but I also often work overtime in the office! There are weekends and holidays in the office! It may take more than a month to go to the countryside for outside work
