Bank of China. The symbol of China Bank is the representative of China's financial and business circles, and it is required to reflect the characteristics of China. The designer used the ancient coins of China and the Chinese character "Zhong" as the basic shapes. In ancient Qian Tu, the frame design was round and square, with a square hole in the middle and vertical lines up and down, forming a "middle" shape, which indicated that the world was round and economy was the foundation. It gives people the impression that it is concise, steady, easy to identify, profound and quite Chinese.
