Did Lao Tzu talk about reincarnation or not?

The real Lao Tzu wrote only one book, The Tao Te Ching, and no other works. Throughout the Tao Te Ching, there is no mention of reincarnation. Samsara is a Buddhist term and has nothing to do with Taoism. By the way, Lao Tzu's thought is Taoism. Although Taoism is now under the guise of Laozi, it is still different from Taoism.
