is a painting theme.

The Picture of Laozi Going through Customs is Fan Ceng's best painting theme. In the painting, Laozi's white hair is floating, his lapel is abrupt, he is as steady as a mountain, but he seems to have no weight at all, and his figure is ethereal, as if he were in front of him. Such a character, how fresh and easy, and how handsome;

The image of Laozi in Fan Ceng's works is full of the spirit of sage-like style, and the clothes lines of Laozi are outlined with powerful lines, which is free and easy. The children who lead the way are filled with smiles on their faces, and the treatment of clothing lines is quite dynamic.

Fan Ceng wrote his own seal script with an inscription, which was rigorous and broad, and his pen was vigorous and powerful, adding a quaint atmosphere to all his works. In 28, Rongbao's 57th auction of fine works of art ended in Asia Hotel, among which a painting "Lao Zi Going through the Customs" by Fan Ceng was sold for 572, yuan, which was the highest price of the auction.

according to Taoist legend, after I left Hangu Pass in the west, my Tao soared, ranking one of the three clean-ups, because I was an old gentleman. It is also said that Laozi is the incarnation of the old gentleman in the sky in this world. However, there was another rumor later, that is, Lao Tzu arrived in Tianzhu after going out to Hangu Pass in the west, and carried out the deed of "turning Hu into Buddha".

Looking at the origin of Buddhism, we find that Sakyamuni and Laozi lived in the same era. One is 563-483 BC and the other is 571-471 BC (the data may be slightly different). It is rumored that Prince Gautama enlightened the Avenue and founded Buddhism at the age of 35, so it was around 528 BC, and at this time Lao Tzu was still in the customs, and it was ten years before he left the Hangu Pass in the west.
