Jiehuan was a Zen monk belonged to the Huanglong school of Linji school in the Sung Dynasty. He wrote three books: The Yao Jie of the Śūrajgama Sūtra（《楞嚴經要解》）, The Yao Jie of the Huayan Sūtra （《華嚴經要解》）, and The Yao Jie of the Lotus Sūtra（《法華經要解》）（for short Yao Jie）. The circle of the Yao Jie, in which Jiehuan blended some sūtras, is the Huayan and Zen. Many scholars think that in addition to Fa-yn, Jizang, Zhiyi, Kuiji, he is the fifth class of the Chinese Lotus school. The characteristic of the Buddhism in the Sung Dynasty is that Confucianism, Buddhism and Taoism were blended stage by stage. At that time, the interior of the Buddhism was integrating. It did not focus on a probe of the deep and extensive doctrine but turn towards to spread up the Buddhist practice of the Zen and Pure Land. Jiehuan quoted the Buddhist sūtras and the sects'' thought extensively in the Yao Jie to explain the Lotus Sūtra. It reflects the blend characteristic of the Sung Dynasty culture. The main ones of the sūtras quoted in the Yao Jie are the Śūrajgama Sūtra, the Huayan Sūtra and the Vimalakīrtinirdeśa. What links every part of the book is the tathāgata pure mind adopted from the Śūrajgama Sūtra. Moreover, though Jiehuan took the thoughts from Tiantai Sect, Faxiang Sect and Zen Sect into his own thought, yet his is influenced by the Huayan Sect most. He emphasized the being has the Buddha-nature. Jiehuan took the Buddha-nature adopted from the Śūrajgama Sūtra as the basis. By this way he compared and adjusted the contents of scripture and the thought of school. As for his attitudes towards annotation, Jiehuan combined inside and outside and applied simple and clear words to annotate the Yao Jie briefly and fluently, without any complicated explanations for the names and appearances. Concerning explaining the title, he pointed out "one mind" is true mind. The sinners and saints are the one and only way. They all have the mind. In the class differentiation, even though how Jiehuan classified the body(正宗分) of the Lotus Sūtra in the Yao Jie is similar to Kuiji, they did not have the same opinion. The Buddha-nature in the Yao Jie is included the without a nature but Kuiji''s is not. The Buddha-nature, the vehicle of one-ness and the practice thoughts are the characteristics of the Yao Jie. In every sect, the Buddha-nature is the core question when referring to the vehicle of one-ness thought. It is also discussed about the vehicle of one-ness of the Lotus Sūtra. Zhiyi thought the sūtra mentioned the complete doctrine of the complete combination and phenomenal identity. Jizang used the Meditatin on the Mean of the Buddha-nature to explain it. Kuiji based on the vijñāna doctrine to understand thoroughly. Jiehuan''s thought of the Buddha-nature was influenced by that in the wholehearted concept of the Śūrajgama Sūtra, so he has the complete combination characteristic. Having the Buddha-nature is why the being has the chance to become a Buddha. The practice method is the wila, samādhi and prajñā. Jiehuan thought the wila is the most important foundation in practicing samādhi. In the prajñā, he thought the Zen meditation should absorb the fundamental substance of the Śūrajgama Sūtra and blen
