In the first year of An 'an in the Eastern Han Dynasty (142), Zhang Daoling was granted the doctrine of "righteousness, alliance and power" or French "three meanings, righteousness and one skill" to establish Taoism.

Therefore, Taoism was founded in the 2nd century.

Sakyamuni lived in the 6th century BC, so Buddhism was founded about 700 years before Taoism.

Buddhism was introduced into China around 1 century.

But Laozi and Sakyamuni are contemporary. Laozi is the founder of Taoism, which is different from Laozi.
