Oriental Shang Qing is wood, so "East Evil" is a yellow medicine (medicine) teacher (usually wearing a blue robe); The south is still red and belongs to the fire, so the "Southern Emperor" yi Deng; The west is still white and belongs to gold, so "Xi Du" is Ouyang "Feng"; The north is still dark and belongs to water, so "North Beggar" is "Hong Qigong"; The center is still yellow and belongs to the earth, so the "magic in the middle" is Wang Zhongyang. Jin Mu's five elements-fire, water and earth-are cleverly embedded in the names of five people.
I hope I can help you. ..
