Why did Tang Gaozong and Wu Zetian use foreign envoys to guard the mausoleum?

There are many reasons why the tombs of Tang Gaozong and Wu Zetian used foreign messengers to wake them up. On the one hand, it was actually relatively developed in the Tang Dynasty, and many foreign envoys had close ties with the Tang Dynasty. Therefore, Tang Gaozong and Wu Zetian wanted to present the prosperity of the Tang Dynasty after their death. They used foreign messengers to wake. And these wake messengers are headless stone statues.

Under the leadership of Tang Gaozong and Wu Zetian, the Tang Dynasty was actually very developed. It was the heyday of the Tang Dynasty. Because the strength of the Tang Dynasty was relatively strong at that time, many foreign tribes surrendered to the rule of the Tang Dynasty. Whenever there are any major ceremonies or festivals in the Tang Dynasty, foreign envoys will come to the Tang Dynasty in advance to congratulate them. It is said that when Tang Gaozong died, many leaders of border ethnic minorities came to attend Tang Gaozong's funeral. Although Tang Gaozong was dead at that time, Wu Zetian was still alive, so among the people buried with Tang Gaozong, Wu Zetian ordered them to be carved into stone statues as Tang Gaozong's wake according to the appearance of foreign envoys who came to attend Tang Gaozong's funeral. I think Wu Zetian definitely did this to show the strength of the Tang Dynasty and let future generations know that the Tang Dynasty was actually a particularly prosperous nation and a particularly powerful dynasty. Many foreign emissaries can only watch the wake for the emperor of the Tang Dynasty. In this regard, Wu Zetian is still relatively strong. Datang really developed well under her rule.

Therefore, when Wu Zetian herself died, she must have given an order, hoping that future generations could arrange for these foreign messengers to wake for herself after her death. Everyone knows that Wu Zetian is one of the few female emperors in China, and she is also a relatively successful female emperor. Many people will obey her orders, so that's why in the graves of Wu Zetian and Tang Gaozong, you will find many mourners as foreign envoys.
