It is difficult and dangerous to embark on this road. How can ordinary people understand it? But how happy is life and how painful is death? The years are only silent. Meeting and getting to know each other is not intentional, but it is most difficult to agree to each other in troubled times. Gratitudes and grievances are spread over thousands of miles, swords and blood shadows, who plays the old tune of the desert. Goodbye is because the dangerous banners will be poured out against the world. There is no need to mention the past. When you and I grow old, our remains will be burned and ashes will be left in history.
