At is used for small locations, with no article in front, in for large locations, with an article in front, on has a fixed collocation, and is rarely used.

In the internal use of the direction in the expression of the direction: shanghai is in the east of China

There is no fixed collocation for this, remember the fixed collocation in the text. The most effective way is to look at the collocation of the phrases at the back of your textbook, and the problem will be solved by memorizing them.

Of course, it depends on what your location is, and it has to be combined with sentences.

Use IN in large places and AT in small places. Use in what and on what top

When I am on the side, I use アット in the inside

Generally speaking, AT is used for small locations, and IN is used for large locations, and there will be a fixed collocation for on.

IN is a big place such as a country or a city, and at a small place, such as home, on the road.
