Tiangang Searching for the Dragon

According to legend since ancient times, when the heaven and earth first opened, the pure air floated up to become the sky, and the turbid air sank to become the earth. However, between heaven and earth, there is still a force of energy that is free from Yin and Yang, called "Dragon Vein". Dragon veins are hidden under the mountains, rivers and swamps, controlling the rise and fall of the world and the flow of fortune. The ancient sages observed the stars, deduced the earth's veins, and discovered that there is a certain mysterious correspondence between the trajectory of the stars in the sky and the movement of the mountains and rivers underground, that is, "images are formed in the sky and formed on the ground."
