There is no path to the mountain of books, only diligence is the way; there is no limit to the sea of learning, only hard work is the boat. Books contain golden houses and beautiful women. If you don't study hard when you are young, you will regret it when you are old. Old classmates: The new semester has begun, you must study hard. Listen to the ancient sayings, receive the ancient teachings, find their taste, think about their meaning, understand their use, and understand their way.
