The tributary system of China was a way for different countries to show respect to the Chinese Emperor. It was like a trade agreement between the Chinese Emperor and other countries.
The countries that wanted to make a deal with China would give the Emperor special gifts, such as money, goods, or even elephants and animals. The Chinese Emperor would then give the countries something special in return, like money or a special honor. The relationship between the two countries was very important, and it was a sign of respect.
The tributary system was also used to spread Chinese culture throughout the world. Other countries learned about Chinese customs and culture through this system, which helped shape the world today!
