It is recommended that you test the authenticity first and work hard to make real objects, otherwise very few people will believe you. You must not contact foreign countries. They are very sensitive to such things and they will never let China appear. Perpetual Motion, so they may be disadvantageous to you. You should apply for a patent at a larger domestic patent office with the actual object. Don't name it as Perpetual Motion. They are too sensitive and you cannot publicize it! China is unable to protect this secret, so it will develop in secret. The benefits will be yours if you insist on publicizing it! China will put you under house arrest, and foreign countries will find ways to make you disappear! I’m not just telling the truth
