I picked up some Chinese words, like ni hao or xie xie simply by being exposed to them so often that it would be impossible to not remember them. I like passive learning activities, like watching YouTube videos or TV shows in Chinese, where I’m repeatedly exposed to various frequent words and I start recognizing them without some dedicated study time.
