I just started generating a custom list to match a book I have called "First thousand words in Chinese" -designed for children so just right for me. On the first 4 pages (78 words) I found at least a dozen new (to Skritter) words. I worry about you guys out there - never used an ironing board or a vacuum cleaner (hoover)? or are you too busy getting thousands of words under your belt to clean up :-). Go pick up the 茶巾 (chá jīn) and dry thoses dishes right now.
