Qingwen is an extremely focused and streamlined Chinese dictionary designed with the Chinese reader in mind. Lookup is meant to be fast and easy. There is just one search field which accepts anything you throw at it – Chinese characters, Pinyin and English – and figures out the most relevant results. Since Qingwen is meant for students of Chinese, you can also easily add words to word lists for future reference and discover relationships between characters by seeing which other words they occur in and which other characters have similar sounds.
