1, promoting the expansion of overseas trade and promoting economic exchanges and development between China and foreign countries.

During Zheng He's voyage to the Western Ocean, he carried out various forms of bilateral trade with the local area on the basis of equality, mutual benefit and exchange of needed goods. He sent China's silk, porcelain, tea, lacquerware, musk, metal products and books abroad in exchange for local spices, medicinal materials, animals and plants, jewelry and raw materials needed for porcelain making. This trade activity has promoted the economic development of China and these countries.

2. Spreading Chinese civilization has promoted the two-way communication and progress between Chinese and foreign cultures.

The Chinese nation has a long history and created a splendid ancient civilization. Zheng He's voyages to the West spread Chinese civilization, such as science and culture, laws and regulations, cultural and educational etiquette, religion and art, brought China's exquisite technology in the fields of architecture, painting, sculpture, clothing and medicine to Asian and African countries, taught local people the techniques of sinking wells, building roads and fishing, popularized agricultural techniques and crop cultivation methods, and popularized currency, calendars and weights and measures. At the same time, the civilization achievements of Asian and African countries were also introduced to China. Zheng He's seven voyages to the West have written a brilliant chapter in the history of cultural exchanges between China and foreign countries.

3. Good-neighborly friendship has consolidated and developed the friendly relations between China and Asian and African countries.

In the mid-Ming Dynasty, China was a powerful country with the highest comprehensive strength in the world. However, China people didn't bully him, and Zheng He's voyage to the Western Seas was recognized as a peaceful journey in the world. Over the past 28 years, Zheng He's fleet has always pursued the foreign policy of "* * * enjoying peace", developed friendly relations with other countries, built a friendship bridge between China and Asian and African countries, and further established the peaceful and friendly image of China.

4. It shows the Chinese nation's dauntless and courageous heroism and open and enterprising mind, leaving us with precious spiritual wealth.

600 years ago, Zheng He and his fleet did not flinch in the face of the vast ocean, the perilous voyage and all kinds of unimaginable difficulties. They persisted with fearless heroism. With the continuous expansion of land contacts with people from all over the world during the Han, Tang, Song and Yuan Dynasties, a new era of the Chinese nation going from the sea to the world was opened, and the exchanges between China and foreign countries were raised to a new level.

Second, the negative impact:

Zheng He's voyages to the West did not aim at making profits from trade, and did not provide strong support for domestic economic development, stimulate the development of handicrafts in China, or promote the development of commodity economy. Instead, he strengthened China's traditional small-scale peasant economy. Moreover, this kind of trade has little to do with the national economy and people's livelihood, because most of the imported goods are high-end consumer luxury goods such as spices and treasures.

At the same time, it also contributed to the enterprising, complacent and arrogant of the feudal rulers in China, which was not conducive to China's political and economic innovation. Zheng He's foreign trade in the Western Seas was not based on equality and mutual benefit.

According to the will of the Ming government, trade adheres to the principle of "favoring one over the other", that is, buying foreign goods at a high price and selling China goods at a low price. Its purpose is only to show the prosperity and affluence of China, thus deepening China people's conceit and self-centered world outlook. The consequence of this kind of trade can only cast a shadow over the development of domestic economy. The huge consumption behind trade has added a huge burden to the people, which is not conducive to social stability in the long run.
