Introduction to yin-yang meridian

Because of its simplicity and accuracy, Tongjing Yin and Yang (Golden Lock and Jade Pass) Feng Shui quickly became popular inside and outside the Great Wall and all over the country, and set off an upsurge of learning geographical Feng Shui in China. For more than ten years, following the painstaking research of various schools of geomantic omen in more than ten non-governmental normal colleges, we have made rigorous theoretical analysis and a lot of practical verification of various schools of geomantic omen, including "Crossing Yin and Yang", and found that "Crossing Yin and Yang (Golden Lock and Jade Pass) geomantic omen" is easy to learn, but it also has the characteristics of "inaccurate quantitative judgment". The use of judgment is unconditional, so mistakes are often made in practice.
