5.“Children are raised with such situations: Looking up at the starry sky and dreaming of flying into the universe, and in the meantime, asking questions and being curious about everything in life. It’s their nature to ask why. After getting older and learning to arm themselves with knowledge, they will gradually remember some whimsical stories in their childhood. Zhihu’s One Hundred Thousand Whys values every question they ask, and thus leading them to the sea of knowledge.
