What were the ways to deal with the civil rights relations of ethnic minorities in the Tang Dynasty?

There were three specific ethnic policies in the Tang Dynasty:

1, pro-family policy, marrying imperial clan women to ethnic minority leaders, such as Emperor Taizong marrying Princess Wencheng to Songzan Gambu;

2. The policy of detention, the appointment of ethnic minority leaders as the magistrate of the detention house, such as Tang Gaozong's establishment of the Hanhai viceroy in the Turkish homeland;

3. For example, the policy of giving money to ethnic minorities when 18 years old, Tang Suzong allowed Uighurs to take money in Luoyang, which was occupied by the Anshi Rebellion.

In the early Tang Dynasty, not only the talents of Turks, Huns, Xianbei, Western Regions, Koguryo and Tubo were used by the empire, but even the Japanese who ate a big meal could be an official in the imperial government. The openness and openness of these talent use policies are unmatched by other dynasties. There seems to be no foreigner being an official in China today. It is this enlightened national policy and open talent strategy that introduced talents from East Asia and Central Asia into the huge ruling institutions of the Tang Empire, which enabled the Tang Empire to give full play to its talents in the vast territory in the early stage, and in a short period of 100 years, it created a vast empire with a vast territory, many nationalities and the most prosperous in the world, against the later Arab Empire. Only the enlightened national policy of the Tang Dynasty Empire-the talent policy that only stresses ability and has no ethnic discrimination, can we create the most magnificent and prosperous empire in ancient China history.
