According to religious legend, Lao Tzu went west to Hanguguan and then to Tianzhu. In history, Lao Tzu has never been seen since. When it comes to China's most representative cultural celebrities from ancient times to the present, Laozi, the pioneer of Taoism in the Spring and Autumn Period and the Warring States Period, is definitely on the list. This well-known thinker, with his own efforts, created a Taoist doctrine that has been passed down through the ages. In his later years, he left a volume of Tao Te Ching, crossed Qingniu and left the Hangu Pass in the West. There are many legends circulating around him: where did he go?

In history, Lao Tzu has never been seen since. If we open the historical records, we can find out? West out of Hangu Pass? That's the end of Laozi's deeds: no one knows where he went afterwards. However, in the Book of the Later Han Dynasty written by Ban Gu, Ban Gu quoted a sentence from the ruling and opposition parties at that time, that is? Or is Lao Tzu a pagoda when he entered the righteous emperor? . In other words, at that time, some people thought that Lao Tzu went to Hangu Pass and then became a monk in the West. Of course, this statement is ridiculous: I ride a green cow, not a high-speed rail. However, due to this discussion, Wang Fu, a Taoist, invented the famous "Hua Hu Jing".

"Hua" is also widely circulated. Turn Hu into Buddha? The origin of allusions. During the Eastern Jin Dynasty when Wang Fu lived, both Buddhism and Taoism flourished, and there were also infighting between them. What does Wang Fu want to prove? Buddha is the Tao? This is why I created China. In this passage? Turn Hu into Buddha? It's not what many people think, is it Laozi enlightened Sakyamuni? ; But? Sakyamuni is one of the doppelgangers of Taishang Laojun? . What does Taoism have? Lao tze eighty-one? According to the statement, the old gentleman in Taishang has eighty-one incarnations; Sakyamuni, the founder of Buddhism, is one of them. So? Buddhism was actually initiated by Lao Tzu? .

Of course, this is just a way of saying that various religions denigrate each other. Later, in the middle of the Tang Dynasty, Buddhists fought back? Turn Hu into Buddha? , and the genesis classics "theory of truth" said? Lao Tzu went west to Hangu Pass to worship Sakyamuni as a teacher? . Around? Go west? Debate is also a reflection of the contradiction between Buddhism and Taoism.
