Idea: The international standard time (unit: hours) of five cities is expressed on the axis, which means that the time on the left is always later than the time on the right. For example, Beijing time is later than Seoul time, and based on London time, we get the above axial chart.

So we can draw the following conclusions:

1. London is 8 hours behind Beijing, so A is wrong;

2. Paris is 7 hours behind Beijing, so B is right;

3. new york is 13 hours later than Beijing, so C is wrong;

4. Seoul is earlier than Beijing 1 hour, so D is wrong.
