Thanksgiving is a traditional holiday in Western countries. It is a three-day holiday and family reunion. At the holiday banquet, there is an indispensable special dish - "roast turkey". Why eat turkey at Thanksgiving? This starts with the origin of Thanksgiving. In 1620, a group of Puritans who advocated reform in England withdrew from the state religion and established their own Protestant religion because their ideals and ambitions could not be realized. This move aroused the hatred of the British authorities. Unable to bear the persecution and discrimination from their rulers, these Puritans took a boat across the ocean and prepared to flee to the United States. After drifting in the sea for 65 days, the ship finally reached the east coast of the United States and landed at the port of Provincetown, Rhode Island. At that time, this area was still a desolate and uncultivated virgin land, and turkeys and other wild animals could be seen everywhere. It was winter, they came to a strange place, they were short of food and clothing, and the harsh environment was threatening their lives. At this critical moment, the local Indians sent them food, daily necessities and production tools, and helped them build their new home. In order to thank the Indians who helped and supported them in times of crisis, and also to thank God for his "gift" to them, on the fourth Thursday of November, the hunted turkeys were made into delicacies and entertained the Indians warmly. , and held a party with them. The celebration lasted for three days.
