Pick one of the street or sit-down interviews on Mandarin Corner (life in a big city, work, family, money) and watch at least ten minutes with the Chinese subtitles on. Then leave a comment in Mandarin giving your own view: do you agree with the person, and why? Two or three sentences, typed with the Pinyin keyboard built into your computer or phone (Windows, macOS, iOS and Android all ship one), or in pinyin.
