Task: Question Generation
Input (English): In addition to strictness in character size and shape, Chinese characters are written with very precise rules. The most important rules regard the strokes employed, stroke placement, and stroke order. Just as each region that uses Chinese characters has standardized character forms, each also has standardized stroke orders, with each standard being different. Most characters can be written with just one correct stroke order, though some words also have many valid stroke orders, which may occasionally result in different stroke counts. Some characters are also written with different stroke orders due to character simplification.
Output (English): What has standardized character forms?
