Hua Yanzong, also known as the first school of sages, is one of the schools of Buddhism in Han Dynasty. This school is based on Hua Yan Jing, so it is called Hua Yan School. The founder is monk Du Shun of Emperor Taizong, the second is Master Yunhua, the third is Master, the fourth is Master Liang Cheng Guan, and the fifth is Master Gui Mi. A?vagho?a and Dragon Tree combined in Song Dynasty to become the seventh ancestor. The actual founder is Fazang, but traditionally the Dragon Tree Bodhisattva is the founder. Because Fazang was named the first Buddhist teacher of the sages, he was called the sages. Lawyer Daoxuan of Datang was in Tianping, Japan for eight years, and entered Japan with Zhang Zongshu of Hua Yan. Silla trial went to Datang, learned Hua Yan from sages, then went to Japan and lived in Da 'anji. There is Hua Yanzong in Japan. Ten sketches say that Hua Yan is the king of strategy, and the secret is in the Dragon Palace. Dragon Tree Bodhisattva recited the sketches with magical power and spread them around the world.

If there is a monk named Tang Dushun, Manjusri Bodhisattva will incarnate. According to ancient records, it was prepared for early ancestors. Following its path, Yunhua-Yan Zhixian began to hide the dharma and even cool the process, and prepared a comprehensive outline. Therefore, the four dharma circles, the ten mysterious gates, the six phases and the five religions are all in the sea of wealth-saving, and the lofty righteousness of Hua Yan is as beautiful as the sun, which is obvious to all. Later scholars, if they want to enter this incredible legal world, they must concentrate on writing on their ancestors.

In the teaching of judging questions, Hua Yan Jing is regarded as the highest classic, and from the thought of Hua Yan Jing, the theory of the origin of dharma circles, the theory of ten mysteries, the theory of four dharma circles and the theory of six phases are developed, giving full play to the theory that everything is fine. This school gradually declined from the prosperous Tang Dynasty to the extinction of Buddhism by Wu Zong.
