What does the initial vertical implementation mean?

At first, it means to stand up and hold it at first. Refers to the "bamboo pole", from Han Danchun's "Lu people see the pole entering the city", selected from "Taiping Guangji". This is a great book compiled by Song people according to unofficial history's novels and explanations from the Han Dynasty to the early Song Dynasty. It is a joke that "Lu people go to town with pole". There are no such stupid people in the world, but this joke tells people a truth: be flexible in everything, not too rigid, flexible and not one-sided and stubborn.
