Disadvantages: without a fixed working environment, the dubbing effect may not meet certain requirements, and it may be recorded separately, and then it will take more time to edit and splice later. The most important thing is that roommates will feel a little embarrassed and may disturb them. And after dubbing too much, you may generally speak in a lower tone, and then others will mistakenly think that you are putting on airs. Don't say no, there are such people in reality. It's ok if you want to earn some pocket money by dubbing, but if you want to take this as your future job but you don't study this major, you still need time to study after graduation and you don't have many opportunities to perform when you first enter this circle, so you still need to work hard!
