"The Complete Collection of Brain Teasers (Super Value Platinum Edition)" selects more than 2,000 brain teasers, divided into "unexpected", "inspiration", "unreasonable", "clever questions and answers", "playing with numbers", "no surprises" and "biting". The eight chapters of "Wen Zhi Zi" and "Guess Who He Is" prepare wonderful humorous feasts for readers and friends, fully mobilizing the vitality of your brain cells, opening up your all-round thinking mode, and making you laugh while making you laugh and have endless aftertaste. Some of the questions are simple and can be solved easily by using reverse thinking; some are difficult and require you to have strong logical reasoning skills like a detective; some are very troublesome and require you to make insinuations and take "evil ways" to get right; some are highly interesting, allowing you to appreciate the wisdom of humor and the magic of knowledge; and some are expressive. It's so confusing now, guess who "he" is... In addition to brain teasers, each part also has two sections: happy dictionary and whimsical thoughts, striving to enable readers to gain extensive knowledge while getting intellectual exercise, to help readers boldly break the inherent thinking patterns, form flexible and changeable ways of thinking, and cultivate humorous, witty, and optimistic characters.
