Introduction to the Eighteen Stairs: On the old street of the ancient town, there is a low slope with little undulations. Because there are exactly eighteen steps here, it is named "Eighteen Stairs". In ancient times, merchants gathered in the Eighteen Staircase, and it was a veritable "small mountain city" with feasting and feasting. Although this place is gradually being forgotten, it is still a symbol of the century-old prosperity of the old street and has important historical significance.
