In ancient China, when soldiers went out to war, what would the monarch say to wish them victory and triumph? Something like martial arts for a long time?

Generally speaking, there was a unique ceremony of going to war in ancient China, but few emperors personally blessed the soldiers who went to war, because it was basically impossible to ask the emperor to appear in front of the troops who went to war. Generally speaking, they will say something encouraging directly to the leading generals.

For example, during the Jiajing period of the Ming Dynasty, there was civil strife in Annan, and Zhu Houzong, the Emperor Shizong of the Ming Dynasty, appointed Minister of War Mao Bowen to go south to settle the chaos in Annan. During Mao Bowen's expedition, Emperor Shizong of Ming Dynasty wrote a poem: "The generals marched across the south in a mighty way, and the wind blew gongs and drums, mountains and rivers, lightning flashed flags, and the sun and the moon shone high." There is a unicorn in the sky. How can the ants in the cave escape? I will bring back a letter safely and unbutton my shirt with the general. "
