The era of great discovery, also known as the era of great exploration, is a historical period of global exploration in Europe, starting from the beginning of15th century and continuing to18th century. This period is considered as a bridge between the Middle Ages and modern times. At that time, western imperialism was just emerging, and European kingdoms competed with each other economically. They want to get wealth through trade routes and colonial plunder. During this period, among many great explorers, Columbus was the most outstanding, because he discovered the new continent, and the expansion of Europe led to the rise of the colonial empire. The contact with Lu Yixin's new road also led to the cultural blending between the two sides, and a large number of plants, animals, food and culture exchanged. This time, it is an important agricultural ecological and cultural blending activity in history. The exploration in Europe makes it possible to draw a global map of the world and let people see a new world that echoes the ancient civilization. (Novice translator, please forgive me)
