What is the status of the special group in the Tang Dynasty-Tang-Japanese hybrids?

Anyone who knows a little about history will probably know that during the heyday of the Tang Dynasty, Chang 'an, the capital of the Tang Dynasty, became an international metropolis. According to historical records, there were many foreigners in Chang 'an, the capital of the Tang Dynasty. There are not only some people from Asian countries, but also some people from distant west and Africa. Therefore, it makes sense to say that the folk customs were very open in the Tang Dynasty. Buddhism was also very popular in the Tang Dynasty. At that time, Japan also sent envoys to the Tang Dynasty for cultural exchanges. During the Tang Dynasty, many Japanese people had settled and lived in the Tang Dynasty. So Sino-Japanese mixed blood already existed at that time. Although Sino-Japanese mixed blood already exists, this group is relatively rare in the Central Plains after all. What was the status of these groups in the Tang Dynasty? In fact, Sino-Japanese mixed blood was an important existence in the Tang Dynasty. After all, the basic people who can come to the Tang Dynasty are relatively important Japanese. Due to some special reasons, these envoys failed to return to Japan smoothly, so they lived in China. Generally, after living in China, these envoys to the Tang Dynasty will still receive preferential treatment from the royal family and will be given some official positions and high status. One of the envoys to the Tang Dynasty had a daughter with a woman in the Tang Dynasty. This daughter is actually not from the Tang Dynasty, so she will go back to Japan to visit relatives in the future.

At that time, there was a daughter who sent envoys to the Tang Dynasty. After a terrible sea voyage, she successfully returned to Japan, which shocked the Japanese nobles. This woman belonged to Fujiwara family, a noble family in Japan at that time, so when this woman returned to Japan, Fujiwara family held a very grand ceremony to welcome her back. It can be seen that the Sino-Japanese mixed blood in the Tang Dynasty is a very important witness to the cultural exchange between the two countries. For the Tang Dynasty, Sino-Japanese mixed blood still existed quite well.
