Maxwell Fa's Enlightenment in the Monastery Chapter 48

On May 15th, just after the You hour, when the sky was still bright, the minor kings and tribal leaders from the Anxi countries entered the Kucha Palace one after another under the escort of Anxi army soldiers.

The Anxi Protectorate had four towns under its jurisdiction. In addition to the four major states of Qiuci, Yutian, Shule and Yanqi, there were also many small states such as Gandhara, Jimo, Yuli, Jianchijian, Zhujubo, Hepantuo, Jingjue, and Khanmi. In addition to these small states, the tribes of the former Western Turkic territories such as Turgesh, Karluk, and Bactria sent princes and envoys to the area.

Ethan Shen stood on the wall of the Kucha Palace, looking at the kings and envoys who were all wearing Tang Dynasty costumes. He couldn't help but ask Feng Changqing beside him, "I thought they came to the banquet and wore their own national costumes. Why are they all wearing Tang Dynasty costumes..."

"The Protector General is hosting a banquet for various countries and tribes. They came here to show their loyalty to the Tang Dynasty. How dare they wear strange clothes?"

Listening to Feng Changqing's words, Ethan Shen looked at the vassal kings, princes and envoys who were attending the banquet. They were all wearing round-necked, long-sleeved clothes and fu hats. He couldn't help but think of the dazzling variety of national costumes in later generations.
