Is the site selection of ancient imperial tombs in China based on geomantic omen?

After the enthronement ceremony in the first year, the new emperor announced the Qin Tian Prison, so he chose the dragon-shaped eternal auspicious place with the best feng shui (which is what we call the imperial tomb)

After Qin chose a piece of land that has been blessed for thousands of years, it will be reported to the emperor, who will personally take people to inspect and approve the best and most satisfactory location of the mausoleum. When the emperor is satisfied, he will take the keepsakes (such as Yu Pei, jade banzhi, sword, etc.) that he carries with him all the year round and throw them away. This is called eye fixation. The location where the eyes are fixed is the location where the mausoleum began to be built. Then you must find the token that the emperor threw you. The place where the token is located is the golden well under the emperor's coffin, and then throw the token with you into the golden well! That's how it was built! After the emperor traveled, he entered the Anfeng tomb.
