Why does the Zhongshan suit have seven buttons, four pockets and three buttons on each cuff?

The Zhongshan suit designed by Sun Yat-sen has the advantages of both Chinese and western clothes. On the basis of Guangdong casual wear, it adds a lapel to the straight collar, just like transplanting a shirt collar into a suit. In this way, the coat has the functions of suit coat, lining and stiff collar, and it looks very stiff when worn. At the same time, the three hidden pockets of casual clothes or general suits are changed into four open pockets, which is so "double" and "positive" that it has a sense of balance and symmetry and conforms to the aesthetic point of view of China people. The upper, lower, left and right pockets are all covered with soft covers, and each pocket has a button, which is beautiful and safe, and can also prevent the items in the pocket from being lost. The following two open bags adopt a flexible "piano bag" style, which is designed to facilitate the placement of books, notebooks and other necessities. Such a trivial matter is enough to prove that a great generation is eager to learn and never forgets the virtue of reading at any time. Sun Yat-sen began to design his coat buttons into seven, and later changed them into five for convenience. This is Sun Yat-sen, with a small lapel, four bags and five buttons, who personally designed new clothes and personally took the lead in wearing them on various occasions. Because this kind of clothing has many advantages, mainly beautiful and generous. You can use high-grade cloth or ordinary cloth. It can be used as a dress or as a daily service. Therefore, it is very popular with the masses and is called "Zhongshan suit". Later, after Sun Yat-sen's vigorous advocacy and promotion, he wore a "Zhongshan suit" for a while, which was highly respected and popular throughout the country.
