I want to be a stage lighting engineer or sound engineer. How long does it take an audio engineer to start from scratch? What are their development prospects?

A lighting engineer can start his career in three months, but it is hard for a sound engineer to say that it may take a year. There are four employment directions. The first is government theater, stable job and salary according to personal relationship, you know. The second performance rental company, the first-tier city with low salary and the most tiring industry, rarely has 5000, which is highly recommended. The performing arts venues in Sanbei are like the Gold Coast, and the salary in Shanghai is between 3,000 and 5,000. The fourth column, short working hours, wages in third-tier cities 4000, first-tier cities 1000. The disadvantage is that it is unstable and needs personal image. I suggest learning lighting and finding a job will be faster than the sound engineer.
