When did Qin Shihuang seal Mount Tai Zen?

In 2 19 BC, Qin Shihuang, the first emperor who unified China, and his ministers set out for Mount Tai, which stood in the east. According to records, due to the difficulty of mountain roads, Qin Shihuang climbed Mount Yi with a cart pulled by sheep. Qin Shihuang recruited Confucian scholars from Lu to discuss amenorrhea etiquette. Confucian scholars said that the etiquette of Zen meditation is very simple, but it is necessary to pay special respect to Mount Tai, and the wheels should be wrapped in pu. Hearing this, Qin Shihuang felt very strange. Thinking that he had been teased, he sent the Confucian scholars away and went straight to Mount Tai. Without unified writing, there will be no unified culture, no unified culture and no unified country. At that time, Qin Shihuang boarded Mount Tai and thought of spreading his unified merits through the ages. Therefore, the national unified and standardized writing bears the great merit of unifying the whole country and is deeply engraved on the eternal Taishan stone. The originator of China Famous Mountain inscribed by Li Si, the prime minister of Qin Dynasty, stood at the top of Mount Tai.
