They helped other people change the world and how they made important mottos. Another thing they did was make people realise how important they are

1st is the Ming Dynasty and 2nd is Qing Dynasty (btw, this is just based on what I’ve learned a bit of the dynasties, so my answers may or may not be entirely correct, hopefully you’ll get this right, and you can shorten my reasons into your own or just what could be said in a shorter response. Good luck!)

Explanation:

1. Majority of the existing Great Wall of China was built in the Ming Era:

- Construction of a unified Great Wall of China was first started in late 3rd century BC during the reign of Qin Shi Huang, the first Emperor of China. However, little of that wall remains. Due to the threat of attacks by Mongolian tribes, the Ming authorities decided to renovate and enhance the wall.

2: Seven Epic Voyages were Led by The - Great Chinese Admiral Zheng He

Yongle emperor of Ming made his favored eunuch Zheng He the admiral of a giant fleet of over 27,000 men. Between 1405 and 1433 Zheng He led seven epic voyages to the Indian Ocean establishing Chinese authority in the region and expanding China’s tributary trade system farther afield than ever before. His fleet traveled as far west as Africa visiting many regions including Brunei, Java, Thailand, India, Arabia and Africa.

2. Qing Dynasty:

- During this period, farmers started producing surplus and selling goods. Trade between villages and regions developed into a robust network, creating the growth of bustling towns like Suzhou. Domestic trade boomed, and merchant guilds were established to facilitate it.

- The Qing Dynasty was the final imperial dynasty in China, lasting from 1644 to 1912. It was an era noted for its initial prosperity and tumultuous final years, and for being only the second time that China was not ruled by the Han people
