"The very best thing about the program is the instant translation feature. It is fabulous being able to zap through a text and look up all the words you don't know instantly. It's the equivalent of an earthbound snail learning to fly."
—Gesa Walker, Edinburgh

"I am thrilled with the program. It is a new and powerful tool in my study of Chinese."
—Jos Spapens

"Your software is by far the greatest Chinese learning tool I've seen, and I am so grateful to you for making available at a reasonable price to the general public."
