First, I'm going with Han Rong. Com, a relatively large intermediary in China. I didn't know anything at that time, and I was charged a lot of money, but the service was very general.
The second time, I contacted the hospital myself. The hospital said that it provided shuttle translation service, but I always couldn't find anyone when I needed someone.
Later, I found an interpreter in Korea through a consulting company.
The third time I went to Korea for consultation was this consulting company called Matten. Personally, I think it is quite cost-effective.
