There are white robes worn by doctors in Guangzhou.

Ah, go to the drugstore to buy it. Most pharmacies sell masks and gloves. White coats are divided into short-sleeved summer clothes and long-sleeved winter clothes. Short-sleeved ones are thinner, and long-sleeved ones should be within 200 yuan. Being a doctor is just a profession. There is no need to feel that it is a pity not to be a doctor.

Ask the drugstore. The one next to our school sells it or buys it online. You can also consider it.
