HOWTO: modify the Pinyin of any Chinese characters

NJStar Chinese WP

For example, I want to enter Pinyin "xue" instead of "xie" to get "blood".

You can modify (add/delete) the pronunciation (Pinyin) of any Chinese character:

Choose "Dictionary Manager" from "Input" menu, then click the "Pinyin..." button;
Enter the Chinese character in "Hanzi:" field; then Pinyin with tone such as "xue3" (for blood) in the field of "Pinyin:"
Click the "Add" button.
