[salc:012] professional

In Japan, there seems to be a classification whether an instructor or an amateur.

The instructor simply means the person who teaches, but people tends to misunderstand like that an instructor should be a professional person.

He/She must be praised as professional person when an instructor organizes some party or plays as a DJ, but neither an amateur is.

As a result, such a sense obstructs the circulation of the tango market.
