It is one of the three components of the wide and narrow alleys, but it has no name, and the attention is also the lowest. However, it also has many characteristics of its own, such as the alley turned a 90-degree bend, the construction of brick walls built with stone bricks of various ages, and the "two-dimensional and half-dimensional" cultural wall that shows the ancient Chengdu humanistic style, which combines with the classical form of the block and increases historical knowledge. It is popular with tourists.
