Family and children / Chapter 30
Section 20 covers the first year after a child is born. Section 18 covers how much money and time raising a child costs. The years in between, ages 3 to 18, are in this section. The item on screen time by age starts at age 0, because the official tiers are 0–3, 3–6, and primary/secondary school; splitting them would make the guidance harder to use. This section answers one question: when “don’t delay schoolwork” collides with “the body,” which things cannot wait. They cannot wait because they have time windows; once missed, they cannot be made up. Whether schoolwork should be that intense is not discussed here — only the windows and the numbers.
The first eight items, item 12 (cycloplegic refraction), item 13 (pit and fissure sealants), items 15 through 19, and item 21 (head hit during sport) are scored on death and lasting physical or mental harm. Among them, items 16 and 17 are about how to parent at home: no hitting or yelling, and take a parenting class that teaches concrete skills. Item 18 is about not sending a child to a closed “internet addiction” school. Item 19 is about teaching a child which body parts are private and to tell you if they were touched. Item 9 (do not buy products that “cure myopia”) and item 20 (do not ride on the road under age) are scored on money. Item 10 (written rules on sleep, homework, PE, and rankings), item 11 (leave of absence with enrollment kept), and item 14 (when a child loves games) are scored on time. Drowning, traffic, helmets, and HPV vaccine are in Section 1. Infants are in Section 20. Scams against children and game top-ups are in Section 5. Red lines minors themselves must not cross are in Section 9. How to recognize an emergency and call a car is in Section 13. Children after a parent dies are in Section 29. None of that is repeated here.

Some illnesses are counted in hours. Sudden severe pain on one side of a boy’s scrotum may be testicular torsion — the vessel feeding the testis twists and blood supply stops. Treated within 6 hours, the testis is saved in 97. …
Scoliosis is a sideways bend of the spine. A brace is a hard shell vest that holds the spine. Worn while bones are still growing, 75% of children never reach a 50-degree curve by the end of growth; observation alone is only 42%. …
Children bullied by peers are about 2.2 times as likely to have suicidal thoughts as those not bullied, and about 2.6 times as likely to have attempted suicide. …
An extra 40 minutes of outdoor class each day in grade 1 cut new myopia over three years from about four in ten to about three in ten. …
The national health commission says ages 0 to 3 get no screens, and ages 3 to 6 should avoid them as much as possible. …
Myopia does not heal on its own, and the degree does not go back down. It is also not only a “wear glasses” matter. …
Primary and secondary schools run one student health check a year. On the report, focus on overweight, obesity, malnutrition, abnormal spinal curvature, poor vision, and dental caries. …
U.S. prevention guidelines recommend screening children aged 12 to 18 for major depression; for age 11 and under the evidence is not enough. In the U.S., suicide is the second cause of death among ages 10 to 19. …
The State Administration for Market Regulation explicitly states that “under current medical technology, myopia cannot be cured.” …
These rules are all laid out in writing: elementary students must get 10 hours of sleep per day, junior high students 9 hours, and high school students 8 hours. Elementary classes generally start no earlier than 8:20 a.m. …
Leave of absence has a formal system. Parents or other guardians apply; after the school confirms, it reports upward for approval. One leave lasts at most 1 year; if more is needed when it ends, apply again. …
Cycloplegic refraction involves using special eye drops that relax the eye’s focusing muscles, allowing an accurate measurement of refractive errors. …
Pit and fissure sealing fills the grooves on the chewing face of big molars with resin so food scraps cannot pack in. Two years after sealing, the chance of cavities is about one eighth of not sealing. …
True “gaming disorder” is about two or three people in a hundred. If questionnaire cutoffs are low and only teens are sampled, the rate looks high. …
Among Chinese secondary students, children who like the same sex or both sexes attempt suicide in a year about 3 to 5.5 times as often as others. …
Children often hit are more aggressive and have more mental problems, are more distant from parents, and get heavier hitting more often. Whether hitting makes a child obey on the spot is unclear in the evidence. …
For children who were already hard to manage, after parents took a class that teaches concrete skills, hitting and rule-breaking went down, and parents’ mood improved. …
The law clearly bans treating internet addiction in ways that harm a child’s body or mind. At a special training school in Hefei, a boy just sent there was cuffed in a solitary room and died about 44 hours later. …
Children who took anti-sexual-abuse classes clearly did more self-protection moves in drills with a pretend stranger. What they learned was still there half a year later, and they did not become more fearful. …
You must be 12 to ride a bicycle on the road, and 16 to ride an e-bike. …
Children who keep playing after concussion take on average 44 days to recover; those taken out at once about 22 days. If something is off after a head hit, do not play again that day — wait until a doctor says yes. …
