Chinese has a number of words with meanings like 'implement, execute, carry out', etc. These include 进行, 实行, 实施, 行使, 落实, 执行, and possibly a few others. These words are commonly used in bureaucratic, official, or journalistic prose, but it is difficult to get a handle on their usage and meaning.
My question is: How are these different words used, and what differences of nuance do they have, if any?
