It is said that n years ago, in a far, far place called N Village, there lived an old man and an old woman. The old man sells tea and the old woman sells eggs. Strange to say, they are a couple, so the old man goes out to sell tea in the morning and the old woman sells eggs, just like year after year. Then there is (omit 200 words) 1 year, where the old man pulls more and the old woman pulls more. Once, the grandson of the old man came to their house and said that his grandparents occasionally wanted to eat eggs. Grandpa said eggs, and grandpa said yes. Grandpa said you should put some water in the pot, and the grandson said, "Good rice, Grandpa. I accidentally got the tea next to the house inside, so my grandson said grandpa's water was ready. Grandpa said you should go and play, and grandson quickly left. Grandpa had a bad eye. When he saw the tea, he put the eggs in, boiled and boiled, and soon it was cooked. Grandson also came back to pull, and grandpa gave him an egg. Grandson said it was delicious, and grandpa also ate it.
