In this lesson we learn the Chinese phrase 失而复得，which literally means you lose someone/something at first but regain back in the end. The meaning is explained through the real life story of 12 boys and their football coach who went exploring in Thailand's Chiang Rai province on 23 June 2018 - but ended up trapped deep inside a cave underneath a mountain. For 2 weeks, news of their rescue efforts gripped the world. Finally on 10 July 2018, the boys and their coach were rescued and all of them were reunited with their families (失而复得).
