The sixth edition of One Hundred Thousand Questions visited 300 schools, distributed 20,000 questionnaires, and collected more than 100,000 questions during the topic selection and planning period. After screening by big data, the 528 questions most asked by children are collected and compiled into a series of One Hundred Thousand Questions that Children Love to Ask. The Science sub-volume contains 66 interesting scientific questions, coupled with exquisite hand-drawn illustrations, making them suitable for children aged 5 to 8 to read.
