Who is the historical prototype of Anyang princess Li Anlan in Tang brick?

Li Anlan's historical prototype is a new princess, the 15th daughter of Li Shimin of Emperor Taizong, whose birth mother is unknown.

(642) Zhenzhu Khan of featherleaf rodgersflower tribe in West Turkic Snow proposed marriage, and Qi Huangong and Li, generals of Emperor Taizong, were captured by Xue featherleaf rodgersflower. In exchange for Qi Qi and Li, he agreed to accept the emerging princess as a pro-Western Turkic.

After Zhenzhu Khan was put back to Qihe Li, Qihe Li persuaded the emperor not to kiss Xue Yantuo, which would only enhance Xue Yantuo's prestige. Emperor Taizong then asked Zhenzhu Khan to personally go to Lingzhou to marry the bride, and hundreds of miscellaneous animals were used as dowry. Due to the snowstorm during the bride price, more than half of the livestock were frozen to death and suffered heavy losses. In 643, Emperor Taizong cancelled his marriage with Xue Yantuo Zhenzhu Khan on the grounds of insufficient dowry, and let the emerging princess marry his eldest daughter Sun Xi.

In the play, Li Anlan was attracted by the Turkish prince Ashina and was asked to kiss him. Li Shimin didn't want to kiss the Turks, but as the internal disasters in the Tang Dynasty became more and more serious, Li Shimin knew that he couldn't go to war with the Turks at this time.

However, when Ye Yun learned that Li Anlan had married a Turk, he left the Turkish team with Li Anlan. Not only that, Ye Yun also used various practical and effective means, which enabled Datang to quickly acquire the strength against the Turks. So the princess of Anyang, Li Anlan, finally succeeded in avoiding the intimate relationship with the Turks.
