Since ancient times, heaven and earth have aura, condensed in mountains and rivers, and outward in the wind and cloud, which is called Long Mai. Where there are treasures in Long Mai, a captain who touches gold will turn his palms in all directions with roulette and divide Yin and Yang into mountains and rivers. This is called dividing gold. Looking for dragons by observing clouds, stars and dragons' points is called looking for dragons. If you look for dragons, you can go to the world. This formula has been passed down from generation to generation, lasting for thousands of years, and is called "dragon-seeking formula" by my colleagues.
