Throughout: 1, from a distance; Comprehensive observation. Look at the big picture 2. From a vertical and historical perspective. Throughout history.
The difference between the two is that "overview" is often used to refer to horizontal comprehensive observation. And "overview" generally refers to the longitudinal historical investigation.
In particular, the meanings of "comprehensive observation" and "comprehensive observation" overlap and the boundaries are unclear. The examples cited are "looking at the overall situation" and "looking at the overall situation", which makes the difference between them tend to be blurred, causing everyone to mistakenly think that "comprehensive observation" means looking at the overall situation, and it seems that there is no difference. "Comparison between the present and the past" focuses on historical observation; "Watching current events" is a kind of horizontal observation focusing on reality.
Listing these two examples with different meanings under the name of "overview" shows that this explanation is inaccurate and unscientific.
In the Dictionary of Modern Chinese Standards edited by Li Xingjian (Chinese Press, Foreign Language Education and Research Press, 1, 2004), the definitions of "overview" and "overview" are: (shift) comprehensive observation.
Looking at the whole field of education. Not the same as "overview". "overview" is often used to refer to a comprehensive observation in a horizontal direction; "Throughout" is often used to refer to a longitudinal historical investigation.
Extended data:
This explanation not only closely follows the original meaning of the words, but also points out the difference between them, which is more accurate and scientific.
By comparing the explanations given in Modern Chinese Dictionary and Modern Chinese Standard Dictionary, we can know that "comprehensive observation" and "comprehensive observation" can be used in general. But we should know that "comprehensive observation" is ≦ "comprehensive observation", because the former focuses on horizontal comprehensive observation and the latter focuses on horizontal comprehensive observation.
