here are two ways of segmenting Chinese characters: form-based segmentation and etymology-based segmentation, which have come up with different conclusions. They, with their own theories and values, are complementary to each other, and serve Chinese character teaching in different ways from different perspectives. Form-based segmentation may produce the minimum form units of characters, which can be arranged into the basic form units. Basic form units can help character learners to get an initial knowledge of the form of characters, and thus to lay a good foundation for character learning.
