The concept of '改革' is deeply rooted in modern Chinese history, particularly associated with the economic reforms initiated by Deng Xiaoping in the late 1970s, which transformed China's economy and society.

Learners often confuse '改革' with '改变' (to change), which is more general. For example, saying '我想要改革我的生活' (I want to reform my life) is incorrect; it should be '我想要改变我的生活' (I want to change my life).
