Who designed the Zhongshan suit? What's the special meaning?

Designed by Sun Yat-sen himself, the government of the Republic of China made it the national costume, meaning: 1 The square bag means "courtesy, justice and shame". The bag cover is an inverted pen container, which means ruling the country by writing. 2. The five buttons on the front represent the separation of the five powers of "administration, legislation, justice, examination and supervision", two more than in the west. The three buttons on the cuff represent the Three People's Principles of "National Rights and People's Livelihood". The whole back represents national unity. 5. Tightening represents strict governance. .
