What's the Yang Cup like?

A positive cup is flat, with one side facing up, just the opposite of a negative cup.

There is no such thing as holy grail, yin cup and yang cup in Buddhism. It is a gimmick for charlatans to add Buddhism to fool ordinary people by saying that the Holy Grail, Yin Cup and Yang Cup are Buddhist. The so-called "cup" is actually a very traditional divination thing like cashew kernel. There are two pieces, each with a flat edge and a protruding edge.

Matters needing attention and main points of divination:

Yuan Hai Zi Ping was compiled by Dasheng Xu in Song Dynasty on the basis of the research results of East China Sea in Xu Ziping. This book is the ancestor of eight-character numerology and a classic of eight-character fortune telling. It is the first book to divide the fate level into three or six levels according to the pattern of financial officials' seals and food injuries. It is the first time to discuss the "four-pillar fortune telling method" completely and systematically, which can be said to be a masterpiece of China's ancient fortune telling.

Tian Di Sui is a numerology book in ancient China, which has a great influence on later generations. Ren Tieqiao, a eight-character numerologist in the Qing Dynasty, aimed at the problem that numerology at that time deviated from the principle of restraint of yin and yang and five elements, which was chaotic and jumbled, emphasizing pattern and evil spirits. Combining with his life's numerology practice, he added notes in chapters, made it clear and subtle, and cleared the source. Taking a large number of human nature as an example, he returned to the road of mission science.
