Believe it or not, creativity can be cultivated, and humor can be acquired subtly, as long as you find the right method! "Classic Brain Teasers", "Funny Brain Teasers" and "Crazy Brain Teasers" in the "Lohas Series" will make you smile after reading each book, enjoy happiness and vitality, and be able to see the fun and creativity in the ordinary. When you know that you can turn around when thinking about things, and you can start from all aspects when observing phenomena, your mind will become more and more sharp, emitting a sparkling golden light. In the future, if an apple falls on your head, you will be like Newton and have some understanding instead of just shouting "Ouch, it hurts!"
