“My students learn on the bus and late at night. Lessons should feel as easy as playing music.”

Mei has taught both languages for twelve years — to commuters, nurses, exchange students and their parents. She writes and records every album herself, in both directions, and listens to every lesson on the 99 B-Line before it ships.
