my fairy tale1

Long long ago,There is was a kind-hearted princess who livesd in a small country. She tucked in up for hibernant hibernating bears, dancinged with butterflies, feeding fed homeless bees, sing and sung with birds in chorus. She is very happinesshappy. As time goes by, she grows up.
Her father, who rules over the kingdom, sends her to married marry a prince who lives in a country around with surrounded by snow mountains.
A few years later, Aan avalanche disaster had strike struck. Several peoples living in this country dead died in this accident. (If you want "disaster" in this sentence, you can say "a disasterous avalanche.")
Wizards say that the princess is a devil who cased caused this accident. The King believed it (better: them) and order the guards to throw her into the dark dungeon.
The news soon spread to the princess's mother country (better: homeland, or home country. "Mother country" is rarely used in English.). Her father announced that anyone who can save her his daughter will get half of the country.
Many volunteers did't didn't come back, until a young farmer stand by (In English, "stand by" means to wait for something. "Came" would be a better verb.). All of the peoples laughed at him for because he can could hardly use a sword.
But he did't didn't have even a little fear. When he arrived the snow country., Hhe was caught either ("Either" is used to indicate a choice: "Either up or down," and doesn't fit here) and thrown into the dark dungeon.
When the guard was snoozing, he the farmer (If you don't say "the farmer" here, then "he" refers to the guard.) stealthily sowed some seeds in the dungeon stealthily .
In a few years, seeds sprouted and broke up the massive wall. Under the cover of darkness, the young farmer escaped with the princess.
After traveling a long way, they returned home successfully. The news quickly spread everywhere quickly. People were all surprised that the young farmer was still alive and come back had returned 
with the jailed princess. The king arranged a personal interview with the young man. The next day the king decided to yield to the brave, patient young man.
At last, the princess fall fell in love with the young king (should be "young man?") and they married.
A happy ending, Iisn't it?

[Good job! Just pay attention to your verb tenses; in a story like this, almost everything will be past tense.]
