Such a free and easy brush calligraphy and verse

This is an ancient poem written in calligraphy, which is very free and easy. The poem means that the wine feast is filled with sweet grapes and wine in a beautiful nightlight cup, and the geisha play a hurried and cheerful pipa to promote drinking, and the soldiers are full of lofty sentiments when they think that they are going to cross the horse to kill the enemy and serve the country. Today must be drunk, even if drunk on the battlefield? The war for the country, originally intended to die, not ready to come back alive.
Very spectacular
