There are two bowls with blue bars on the side, which can generally be traced back to the Cultural Revolution. It is also called "Double Blue Bar Bowl".

This kind of bowl is characterized by no color, no gaudiness and moderate size, which is estimated to hold half a catty of rice. There are two pure blue edges near the bowl.

This kind of bowl was widely used in 1970s and 1980s. Because of its obvious characteristics, it became a memory symbol of that era.

Please note that with the passage of time and the replacement of generations, this kind of bowl may appear in some historical collections or retro-style designs, so there may be opportunities to see this kind of bowl in modern times.
