I think we should write from the comparison why there are new routes in Europe but not in China.

The reasons can be as follows: 1. The enlightened degree of the ruler. 2. The role of religion (both Spain and Portugal have the motivation to preach). 3. The bourgeoisie found that the bourgeoisie in China was oppressed by heavy feudal rule.

Finally, talk about the impact. Since it is China and the world, throwing should be combined. Because of the opening of new air routes, China began to lag behind Europe. With the great development of capitalism in Europe, the preliminary division of colonies has become possible.

You go to see the documentary about the rise of great powers, and watch the episodes of Spain, the Netherlands and Portugal. It's comprehensive. This documentary is very good. It is necessary to study history. It's not boring at all, full of epic feeling.
