This is from the Standard Course Book of HSK5, chapter 12.
What is the meaning of 在经营销售上?
At the moment I am here:
在经营销售上 = 在［经营销售］上 = in managing / operating selling
What means managing selling or operating selling?
Baidu translate: In terms of operation and sales
Google translate: In terms of business sales
Where these translation engines found the word "terms"?
In any case, I cannot understand what this sentence mean.
在 经营(和)销售 上 - On operation and marketing
"In terms of" means "talking about", "Regarding", "As far as XX is concerned"
terms are words.
Chinese doesn't really distinguish verbs and nouns, so if you think 经营 means operate, a verb, well, it may just be operation(s), a noun, likewise 销售.
在经营销售上，
As far as operations and sales are concerned,
