Mantra:

One point went up to the sky, the Yellow River two bays, eight big open mouth, the word to go inside, you a twist I twist, you a long I long, the middle plus a horse king, the bottom of the heart word next to the moon, leaving a hook to hang the hemp sugar, sitting in the car car to stroll in Xianyang.
