Buddhism began to spread Zen in China, "pointing to people's hearts, regarding nature as Buddha, not writing words, teaching people". Not writing means that Zen is divorced from words, and language and words are just code names that describe everything. This is also the reason why Huineng knows no one, but is familiar with Buddhist scriptures. As long as you know your heart and nature, you can become a Buddha. After the second ancestor Hui Ke, the third ancestor Sanshen, the fourth ancestor Daoxin, the fifth ancestor Hongren and the sixth ancestor Huineng vigorously promoted, it finally blossomed and became the first gate of Buddhism in China. Later generations respected Dharma as the ancestor of Zen in China and Shaolin Temple as the ancestor of Zen in China.
