1 The book has its own golden house, and the book has its own beauty like jade. There are thousands of grains of millet in the book, and there are many chariots and horses in the book
2 No one cares about me in the cold window for ten years, but I become famous all over the world in one day
3 The white hair in the window makes me sad , The blue head at the bottom of the candle encourages reading.
Don’t miss a single word when reading, and I will be shocked when I close my door.
4 You will regret less when the book is used.
