The old lady said she was grinding the needle. Li Bai was surprised. He thought, how can an iron pestle be ground into a needle when it is so thick? The old woman said that as long as the kung fu is deep, the iron pestle is ground into a needle. Hearing this, Li Bai was ashamed of himself. He turned and ran back to the bookstore.

Therefore, in order to develop electric lights, Edison often worked in the laboratory for more than ten hours a day, sometimes for several days. After he invented carbon fiber, he experimented with more than 6,000 kinds of plant fibers, but he never gave up. Finally, he chose bamboo filaments, burned them in a high-temperature closed furnace and reprocessed them to obtain carbonized bamboo filaments, and put them into a light bulb to improve the vacuum degree of the light bulb again, so that the light bulb can be continuously lit for 1200 hours.
