Hello, it depends on whether they have a medical license at home. It is illegal to have only a medical license, and it is legal if they have a medical license at home at the same time. If they don't, it's illegal, just like tongue twisters, because the medical licenses of hospital doctors are very limited. For example, the internal medicine department is on the ninth floor, and he can only legally practice medicine on the ninth floor. When he leaves the gate, it is not within his medical scope. This also makes many doctors afraid to see a doctor outside.
