2. Ping Wu An's geomantic metaphor means that everything is safe and everything is fine. Lu Zigang, a famous jade sculptor in the Ming Dynasty, made a name for himself by integrating stamps, calligraphy and artistic creation into jade tablets. Later people called it "Zigang Brand", and one of them was completely blank, named "No (Decorative) Brand", which was deeply loved by everyone and widely known. Buddha said: Nothing means being, and nothing means everything. Therefore, the "safety card" is regarded as the "wish card", and everyone competes for it. I heard that if you write your wishes or wishes on the "safe card", your wishes will come true and wait for you all your life.
