Physical requirements of KTV for employees to go to work

Hello! You don't need to go to a big hospital to sign in to work in KTV, and you don't need any health certificate, because you are a cashier. I have been working in KTV, and I am a sound engineer. I have worked in the three major KTV's for more than five years, and I know the process inside, so I don't need to check it as long as it doesn't involve eating and drinking. You can go to work with peace of mind, but you'd better not talk about your illness between you and the employees. There are many reasons. At the same time, I hope your illness will recover soon. . . . . . .
