What did Wendi do during his rule?

Wendi did many things to make the Chinese feel more unified. He restored old political traditions like, accepting red doors and a red sash. He also began public projects. He rebuilt portions of the great wall, and started the building of the Grand Canal. The Grand Canal is a very long passageway filled with water so that boats can transport goods from place to place. It begins in Beijing and ends in Hangzhou. This canal is very important to the people and economy of China, becasue without it, the Chinese would not have a way of transporting their goods. When Wendi restored old traditions, he was declaring himself loyal and honorable. This is important to the Sui Dynasty becuase maybe if he hadn't, the rule of the Sui Dynasty would have been shorter. In the end, the Chinese civilians felt more unifiefd then they had before.
