Sanjieyi is an intangible trademark. The intangible trademark "Sanjieyi", a heroic brand of the Chinese nation for 2, years, refers to an idea trademark that has no physical form, but is produced in the brain by a series of communicative thoughts, consciousness or senses. The earliest intangible trademark in China was the "Sanjieyi" brand in the Three Kingdoms period. When Liu Bei, Guan Yu and Zhang Fei are mentioned, people will always associate them with their early years in Taoyuan, which is in full bloom after Zhangfeizhuang in Zhuojun County. They prepared black cows and white horses, offered sacrifices to heaven and earth, burned incense and worshipped again, and became half-brothers. They did not expect to be born on the same day in the same year, but only wished to die on the same day in the same year. The "Three Boundaries of Righteousness" led to the three main heroes in the Three Kingdoms period, which showed the theme of loyalty in many ways. Liu Bei of the Han Dynasty was trying to regain the world for the sake of losing it, but he couldn't keep the world or fight the world without three pieces of benevolence, righteousness and courage. Liu Bei was confident that the "benevolence" he inherited from zhongshan jing wang was quite genuine, only lacking righteousness and courage, so he pulled Guan Yu and Zhang Fei.

Estimation of the value of intangible trademarks: Liu Bei gave full play to his brand of "Sanjieyi", and the loyalty strategy he advocated was almost unmatched by anyone else. His life ideals of "obeying the righteousness" and "being comfortable with the people" finally made him the "king of righteousness" in the minds of his generals. After nearly two thousand years of baptism, the brand image of "Sanjieyi" has been deeply rooted in people's hearts. It is a symbol of Chinese national morality and a historical and cultural heritage of China! During the following two thousand years, there appeared quite a number of intangible trademarks in China, such as Tong Ren Tang, which means to be in harmony with others, broad and selfless, and to treat people equally regardless of their closeness. The origin of Goubuli: The boy who once studied in the steaming shop was named "Gouzi", and later he opened a steamed bun shop. His business there was very prosperous, and the dog was too busy to talk to the guests. As a result, people who ate steamed buns all said that "the dog sold steamed buns and ignored people", and for a long time, they called him "Goubuli". The origin of Zhang Xiaoquan: It is said that there was a blacksmith named "Zhang Xiaoquan" because his mother fell into the spring with a splash when she gave birth to him. Since Zhang Xiaoquan made scissors, it's convenient for everyone to cut them if they want. Since then, Zhang Xiaoquan has become a representative of the scissors industry! These brands were originally titles that were subconsciously formed in people's minds by a certain concept. If they persist in the past, they will become intangible trademarks. When the firmness, breadth of use, usability and influence of an intangible trademark reach its peak, its value is limitless!
