The Chinese pinyin had been taught in the second meeting. I invited my friends to join our class. I showed them all pinyin and told them how to pronounce it. I found that some they can learn very quickly and some were very difficult for them to pronounce because there is not this pronunciation in their own language. I thought the most difficult pinyin was ü. Another big change is tones because there are four tones in each pinyin and each tone have own mean. But don’t worry! Practice makes perfect!
