As far as I know, the chopsticks culture in China cuisine can be traced back to Shang Dynasty.

Chopsticks are one of many splendid cultures in China. It is understood that the description and textual research of chopsticks appeared in Shang Dynasty. At first, chopsticks were mainly made of copper, and later, in the later research, scholars found that there were traces of chopsticks in some archaeological materials, such as murals, ancient tombs, patterns and images on bronzes, and funerary objects, although the shapes and forms of chopsticks in the past were different from those of our chopsticks now. In addition, according to legend, Dayu was the first human to use chopsticks because of the harsh environment and emergency.

In short, chopsticks culture is one of the excellent cultures in China, with a long history.
