I've removed notes with duplicate words like singular 是, 谁, 我, have culled any notes with improperly clipped audio and have removed notes with non-Mandarin audio.
Comes with cards that train:
English to Mandarin (you read the English, flip to hear/see Mandarin)
Mandarin reading to English (you read the Mandarin, flip to hear Mandarin/read English)
Mandarin listening to English (you hear the mandarin, flip to read Mandarin/English)
