What major should I study after graduating from junior high school?

What major should I study after graduating from junior high school is really hard to say, because I don't know where my hobbies are. But in general, junior high schools can say that the majors are:

1.IT industry: software development technology, software testing technology, network engineering technology, etc.

2. Medical industry: male nursing major, etc.

3. Tourism industry: tour guide, tourism management, hotel management, etc.

4. Sales industry: network promotion, network marketing, etc.

5. Others: chef, auto repair, numerical control, customer service, etc.

What to learn depends on yourself. The graduation age of junior high school is too small for Zhenggui, less than 18 years old, so we should consider it clearly.
