Can you write four seven-character poems without following the rules?

There have been many hardships since ancient times, but how sad is this world? Tears of heroes on the battlefield, wounded in the attic. But I asked that man to honor his hometown, and I saw Marco come back to life? The soul of a strong man is still there, and the scholar returns to serve the country! Bring wine and sword to tell elders and lead Ma Zhi barbarians. Swear to be equal to you, but seek a good name in history!

Since ancient times, mountains and rivers have always suffered; How much sadness is there in the world today? How many blood and tears did the hero shed on the battlefield? In the attic, Iraqis are playing the piano. How sad is it? Men just want to go home, but most of them are old horses. When a strong person dies, his spirit will last forever! Scholar's spirit, vowed to serve the country. Take wine, take a sword, and bid farewell to the villagers; Lead the horse, put on armor and fight the barbarians. Vowed to help the king pacify the world! Just ask, your good name, the history of history!
