1.　Before every New Year or major celebrations, there would be a general cleaning. The room could usually be kept tidy for a couple of months, but often it was a matter of only a few days before the room was a mess again, and that was mainly due to those books, piles of books, everywhere. Whenever I was out on business, I couldn't help going to bookstores, and once I was there, I could never resist the temptation of buying more .New books, books that I had a thought of reading, books of which I only finished half, books needed for my writing, and books that had values to keep took up most of the space in my room, and they were ever expanding, eating up a11the time the remaining part of my room that provided the minimum space for me as the dweller there. Isn't this an invasion? But I accepted invasion of such kind with comfort and pleasure.

　　2.Children are not sophisticated. They do not love money or reputation, or those big and magnificent houses. If they are hurt by someone, they cry it off. That is why they usually fall to sound sleep once their heads touch the pillow, and they enjoy the best-quality sleep in the world.

　　Children arc always curious. They are always fancying and thinking, and their brain is always in a happy whirl. A strangely-shaped cloud, a rarely-seen leaf, all these will arouse endless associations from them. The same life, in children's eyes, will present pleasures and happiness which we grown-ups can never imagine.
