Yǒu dàoli, dàn hái yǒu ge wèntí.
Fair point, but there is one more problem.
Concede first, object second. The opening three words are not decoration, they are what makes the but hearable.
REAL SPOKEN CHINESE
Give ground first, then state your view. The Chinese pattern is you have a point, but, or I see it a bit differently, which leaves the other person's face intact while still saying no to the idea. A flat you are wrong exists, but it belongs to close friends and arguments.

Wǒ bú tài tóngyì.
I do not quite agree.
The bu tai shrinks the disagreement to a safe size. Dropping it turns the same sentence into a confrontation.
Wǒ dào bù zhème kàn.
I actually see it differently.
The dao softens by sounding thoughtful rather than opposed. Good for disagreeing upward, with a boss or a senior.
Zhège wǒ zài xiǎngxiang.
Let me think about this one more.
Postponement as disagreement. When you cannot say no in the room, buying time is the respectful way to not say yes.
Huà bù néng zhème shuō.
You cannot put it that way.
Objecting to the framing, not the person. Among peers this is fair pushback, aimed at a superior it would sound like a lecture.
Nà yě bù yídìng.
That is not necessarily true.
Five words of doubt with no attack in them. It invites them to prove their point instead of forcing you to disprove it.
Nǐ xiǎng duō le.
You are overthinking it.
Dismisses the worry while implying they are the anxious type. Fine with friends, risky with anyone keeping score.
Lādǎo ba.
Oh, give me a break.
Total dismissal between close friends, usually with a laugh. To anyone else this says your idea is not worth answering.
Chě shénme ne.
What nonsense are you on about.
Che is talking rubbish. Between mates it is affectionate, to a stranger it is calling them a liar to their face.
