The logo of China Unicom evolved from the circular pattern of "disc length" in ancient China. The circuitous lines symbolize the modern communication network, which means that China Unicom's communication business is orderly, swift and smooth in the information society, and also symbolizes that China Unicom's business is endless and enduring.

The four squares in the logo shape have the meaning of extending in all directions, and everything goes well. Six circles are connected by roads, which are smooth everywhere, while the ten holes in the sign have endless and perfect meanings. No matter from symmetry or even number, it is permeated with the auspicious spirit of the long-lost ancient East.

The logo of China Unicom also has two obvious "hearts" connected from top to bottom, which clearly shows the purpose of Unicom: communication, communication, and Unicom will always be considerate of users and heart to heart with users.
