Inspired by the origin of The Hanoi Old Quarter. The name originates from 36 guilds of the craftsmen and merchants who divided the area according to their specialties in the 15th century. which were workshop areas, not streets. When streets were later developed, the guild names were applied to the streets. Others attribute the 36 to a more abstract concept. The number nine in Asia represents the concept of "plenty". Nine times the four directions make 36, which simply means "many". There are now more than 70 streets in the area.
