Under his twenty-three years rule, he did the great job more than any emperor before him. Taizong reformed agriculture, manufacturing and commerce. As the improvements achieved in both agricultural and manufacturing production were surpluses that was available for foreign trade. This made the country first strong economy and the commercial enterprise throughtout the world.
Among the manufacturing industries that became highly developed were porcelain production, bronze and iron smelting and casting, shipbuilding, and textiles with new techniques for weaving and dyeing.
Political progress was achieved by the overhaul of the examination system first introduced by the Sui for the appointment of officials. This system ensured that administrators were selected on merit rather than nepotism or bribery. In this way only the best men were appointed to vital posts within the government of the country. Political corruption was virtually unknown as a result of these sound administrative structures. The transport system was improved. The improvement of roads and waterway connections between important cities. This also strengthened border protection.
The strong economical and commercial were traded with Japan, Persia, Arabia, India and Korea. This factors let the period with TaiZong's reign was refered to as "The Prosperity of Zhenguan". Taizong would remind himself of this frequently by quoting a maxim of the great philosopher, Zhuangzi, 'the waters can both float and capsize a vessel.' The emperor clearly understood how these words were a metaphor for his relationship with the empire that the peasant classes were proved to be a very dangerous against government. With the people satisfied and enjoyed the standard of living that could lead to a long empire. There were two factors that ensured the political stability he sought to achieve. 1. to pick the right person for the work. 2. to seek the opinions of others before making a decision. Taizong's only accepted a man's ability regardless of his background. There were many important official came from lower class. Yuchi Jingde was a former blacksmith which became one of his ministers. Qinqiong, a minor official was appointed as a minister. Emperor Taizong's willingness to listen to the opinions of others and his ability to both seek and act upon good advice was a major factor of his successful reign.
