What does "66 Dashun" mean?

First, it should come from "three three inexhaustible, six six infinite"

In China's traditional concept, "three" is a number that can be extended indefinitely.

By extension, the multiple of "three" has the same property.

For example, Liuhe, Nine Days, Eighteen and Hundred Single Eight Heroes.

In fact, these figures all have extremely "big" meanings.

Furthermore, "six" and "slippery" are homophonic, and "smooth" and "six" can be linked.

Therefore, the "six" and "smooth" can be combined indefinitely.

The words of the family, please correct me!
