Ouyang Miguo's "Registration Certificate of Studies on Heaven and Man"
Ouyang Miguo and his apprentice showed "patent certificates" everywhere in nine days, saying that they have the patent of the idea of learning between man and nature, which is of course true. Those who question it, those who make irresponsible remarks about Ouyang Miguo and his disciples displaying the "patent certificate" everywhere for nine days, can apply for registration by themselves!
