"Learning this physiology through comics is far easier to take in than sitting together red-faced while a biology teacher lectures on it."

"Even someone over 30 reads it and suddenly gets it; the illustrations and witty text make it so plain that it saves ten years of professional reading."
—Douban reader

"With the help of comic explanations, it really lets kids learn puberty health knowledge with poise; compared with the stiff lectures and purely medical illustrations in biology class, the content of Half-Hour Comics Adolescence is far easier for children to accept and understand."

Puberty, made laugh-out-loud simple: body, mind, friends, and safety—one set for the whole journey.

For every teenager wrestling with the confusion of puberty. What exactly is the "Aunt Flo" girls talk about? Why do girls' breasts grow? Why, the moment puberty hits, do we sprout body hair and break out in acne? Why does a boy's voice crack into a "duck quack" at puberty? Why does your face flush and heart race around a crush—am I "abnormal"? Adults panic about puppy love, but what on earth is love? Mom, where do I really come from? These are questions every boy and girl is too shy to ask and every parent struggles to answer—yet no one makes them easy to understand. Half-Hour Comics Adolescence: Physiology turns forbidding puberty biology into something as easy as reading a joke, through hand-drawn comics. The book has nine chapters that systematically explain the health knowledge and common myths of puberty: "Aunt Flo" is actually the demolition of the egg's "wedding chamber"; breast growth is the two hormone sisters' hard-fought startup saga; acne is a "tragedy" set off by androgens, where the sebum meant to protect skin becomes the fuse of an immune war; a sperm's journey to maturity is no easier than the gaokao; blushing and budding romance are actually a "game" played by nerves and hormones. It also covers nocturnal emission, voice change, how life begins, and self-protection. This is not a textbook that makes you sit up straight, but a book that slips puberty knowledge into your head between laughs. Open it to understand the physiological reasons behind bodily changes—no confusion in youth, no worries in growing up.
