The use of bamboo tubes for communication is an important means for people to communicate socially.
Bamboo Tube Message
In November of the 11th year of the founding of Emperor Wen of the Sui Dynasty (590), Yang Su led the navy to cross the river and enter the south of the Yangtze River to quell the war, and fought several victorious battles. . Yang Su worked hard and led the main force to track the rebels all the way to the seaside. Facing the rolling mountains and the vast sea, Yang Su ordered the large troops to be stationed on the spot. At the same time, he appointed the marching commander Shi Wansui to lead an army of 2,000 people to cross the mountains and ridges to attack behind the rebels.
Shi Wansui led his troops to advance rapidly, fought many victorious battles, and recovered large areas of lost territory. When he wanted to report the victory to his superiors, he was unable to get in touch with the large troops due to traffic obstruction and poor information. One day, he stood on the top of the mountain and looked into the wind. He saw the dense bamboo forest in front of him dancing in waves with the wind. After it is done, put it into the water and let it drift down.
A few days later, a villager who carried water saw the bamboo tube and the report sealed by Shi Wansui inside, and delivered it to Yang Su according to the instructions on the report. Immediately reported to the imperial court the successive victories of Shi Wansui's troops. When Emperor Wen of the Sui Dynasty heard the good news, Long Yan was overjoyed and immediately promoted Shi Wansui to the rank of general of the left army. Then, Yang Su led a large force and continued to pursue the anti-Sui stragglers in pursuit of the victory. It didn't take long to completely put down the rebellion.

Other communication methods
1. Fenghuo
Fenghuo is a simple and fast communication method, which is very suitable for plains Or used in mountainous areas. During the Anti-Japanese War, in order to prevent Japanese sneak attacks, villagers placed message trees on the top of the mountain. When they saw the enemy, they would knock them down to warn the surrounding people. This point is probably based on the role of beacon fire.
2. Flying pigeons
According to the "Book of Mountains and Seas": There are three blue birds beside the Queen Mother of the West. They can fly across thousands of mountains and rivers to convey messages and spread happiness and joy to the world. Legend has it that the Queen Mother of the West once wrote a letter to Emperor Wu of the Han Dynasty Liu Che, and at that time she sent a blue bird to deliver the letter to Emperor Wu of the Han Dynasty. Later generations used birds like swan geese to communicate with each other, which gradually evolved into flying pigeons to pass messages.
