My name is to you. Teach you two tips:

1. First, find the observation point. For example, XXX is 30 east of AAA, then AAA is the observation point, and the place behind the word "in" is the observation point. This is very important and must be remembered;

2. When you are observing, you can draw a cross at the observation point, mark it east, west, north and south, and draw it according to the conditions of the topic. For example, the east is 30 north latitude, so you can draw an angle of 30 north in the east.

I hope you can tide over the difficulties with my help!
