When I was a student, I really felt that modern history was particularly difficult.

In order to remember the modern history, I made a very long modern history calendar.

Then according to the time, all the historical events and historical influences in modern history are written on it.

Basically, the test sites of modern history have been added to their own calendars.

After that, I will hang my calendar in front of my desk, and when I am free, I will read it from beginning to end and slowly recite the modern history.
