I would like to know an equivalent word for "by far" in Mandarin, when it comes to the superlative degree (最～）.
In this sentence, it just means 最多, while it does not mention the degree of it. It might be 40%, or 25%, or 79%. It is natural to say it is "最多" as it is the first reason here, but it is unclear if it is "by far" or "barely ahead of the second".
But when the first choice consists of 79% while the second one is just 9%, I would rather like to use "by far" or its equivalent word to emphasize it.
The Chinese grammar wiki's section on superlative 最 does not mention the emphasis.
Does this kind of word or expression exist in Mandarin?
