Hundreds of millions of miles east of the Bohai Sea, there is a large ravine, which is actually a bottomless valley with no bottom below it, so it is called Riguixu. The water of the Eight Strings and Nine Fields, the currents of the Heaven and the Han Dynasty, are all poured into it, without increasing or decreasing. Among them are five mountains: Daiyu on the first day, Yuanqiao on the second day, Fanghu on the third day, Yingzhou on the fourth day, and Penglai on the fifth day.
May you live in Chang'an in the future, and hope you will live in peace for the rest of your life.
