Which part of the body does local refer to?

Part does not refer to a certain part, but to a certain part of the whole. For example, in the weather forecast, some areas have rain, and some refer to uncertain areas. In the same city, there is rain in the south and no rain in the north, so the south is a local area of the city. The source of the word "local" is Lu Xun's "Mr. Fujino": "This time Mr. Fujino's homework is anatomical practice and local anatomy."

Local refers to a certain part of the body, not the whole body. This part is not sure where it is, that is, somewhere in the whole body. It is suggested that everyone pay attention to hygiene, take a bath frequently and wear pure cotton clothes. Personal clothes should be disinfected regularly, exposed to the sun, or scalded with boiling water.
