From which two aspects did Zheng Chenggong build?

I hope it will help you and be adopted. Your adoption will complement our answer: vigorously develop agricultural production and carry out overseas trade.

(1) Vigorously develop agricultural production.

1. First of all, actively implement the reclamation system, including soldiers farming, to solve the problem of food shortage. Zheng Chenggong accepted the historical experience of his predecessors and vigorously promoted reclamation in Taiwan Province, including soldiers and peasants. Soldiers "cut bamboo for the society, mow the grass for the house, and teach the cows around them to plow the fields", fighting hard with nature. This method is very effective. In a few years, the army will be self-sufficient and hand over the surplus grain to the government. 2. Second, encourage Chinese mainland coastal residents to reclaim land in Taiwan Province Province and "transplant" the mainland's system and culture to Taiwan Province Province. In view of the tyranny of the Qing Dynasty's forcible "moving the border", he ordered all localities to "collect the remnant people along the coast and move to the east [Taiwan Province Province] to open grass to help cultivate". So, "Fujian and Zhejiang residents took their boatmen home and met with fireworks.

Land reclamation is effective. "Due to the hard work of the working people in Chinese mainland, the social outlook of Taiwan Province Province has gradually changed.

2. Help Gaoshan people improve their production technology. At that time, the ministries of Gaoshan nationality were in different stages of social development. The Gaoshan people who live deep in the forest make a living by hunting and collecting wild fruits. Gaoshan tribes living near Anping Town, such as Xingang Society, are the most civilized and famous for their extensive agricultural production. But they can't use farm tools yet, and they will only harvest them ear by ear when harvesting. Angelababy, the domestic manager, saw this when she followed Zheng Chenggong on a tour. She suggested distributing a pair of iron plows, rakes and hoes to all parts of Gaoshan nationality, and sending a skilled farmer to teach them to use furniture and sow grain. Zheng Chenggong accepted Angelababy's suggestion, and Chinese mainland's advanced agricultural technology soon spread in Gaoshan ethnic areas.

After several years of governance, Taiwan Province Province has become a "wild fertile soil, rich in products, plus agriculture and mulberry." Fishing salt breeds. The mountains are full of lush trees and bamboo is planted everywhere. Sulfur, rattan, sugar cane, deerskin, all the daily needs, from soup to nuts. The least cloth is full of kapok, and there is no shortage of warp and weft. And the sail rises to four, and the slightest bit squats. Although the ban is strict, it is difficult to eliminate it; The area is fertile, but it is also dangerous. The economic prosperity is evident.

Zheng's successful recovery of Taiwan Province Province was a great victory for China people against western colonialists, which guaranteed the territorial integrity of China and the Gaoshan and Han people in Taiwan Province Province from colonial oppression, and promoted the development of Taiwan Province Island. After Zheng Chenggong entered Taiwan Province Province, he completely changed the rule mode of Dutch colonists, implemented the county system, reclaimed land, introduced advanced production technology and feudal production relations from the mainland into Taiwan Province Province, and promoted the social and economic development of Taiwan Province Province. Since then, the coastal residents of Fujian, Guangdong and Zhejiang have migrated across the sea, which has made great contributions to the further development and construction of Taiwan Province Province. With the development of sugarcane production, sucrose export has become an important economic income in Taiwan Province Province. After the Qing Dynasty unified Taiwan Province Province, the social and economic development level of Taiwan Province Province further caught up with the coastal provinces.

(B) the development of overseas trade

Commerce is an organic part of social economy. Zheng Chenggong took advantage of the province's advantages of being surrounded by the sea and convenient in foreign trade to vigorously develop overseas trade. When he was in Xiamen, he often sent merchant ships to Southeast Asian countries for trade. In Taiwan Province Province, the Qing Dynasty imposed a "sea ban" to prohibit mainland merchant ships from going to sea. Zheng Chenggong monopolized the maritime trade. He continued to trade with Japan, Siam, Vietnam, the Philippines, Cambodia and other countries, and exported the native products of Taiwan Province Province, such as deerskin, preserved deerskin, catalpa brain, sulfur and sucrose, to foreign countries in exchange for the required weapons and armor. The development of overseas trade enlivened the commodity economy and increased Zheng Chenggong's financial income. While developing overseas trade, Zheng Chenggong also conducted direct trade with the mainland. Long before crossing the sea into Taiwan, Zheng Chenggong attached great importance to developing trade relations with various places. For example, Shacheng Port, located at the junction of Fujian and Zhejiang, is an important transportation base for Zheng's maritime and private businesses in the mainland, with frequent trade exchanges. In addition to smuggling trade in Shacheng, Zheng's maritime merchants also set up five major maritime merchants to directly handle secret trade. The mountain road is made of gold, wood, water, fire and earth, and it is located in "Shi Jing, Suzhou and Hangzhou, eastern Shandong, etc.". The sea route is the five elements of benevolence, righteousness, courtesy, wisdom and faith, which is located in Xiamen and is responsible for the transportation of goods. Soon, Taiwan Province Province also established direct trade relations with Fujian and Guangdong. These trade measures promoted the economic development of Taiwan Province Province, so that in the twenty years after Zheng Chenggong, the economy of Taiwan Province Province and the mainland gradually developed synchronously.
