The Chinese characters “枥枢” are pronounced as “lì shū”. In English pronunciation, “lì” can be approximated as “lee”. And “shū” can be pronounced similar to “shoe”. These two characters are not very common in daily language. When learning Chinese pronunciation, it's important to pay attention to the tones as well. Different tones can completely change the meaning of a word. Mastering the pronunciation of Chinese characters takes practice and patience.
