你有什么建议吗？

Place it at the end of a problem description. For example, 'I am hungry, but I hate salad. 你有什么建议吗？'. You can also swap 你 (you) for 您 (polite you) in business. It is a grammatically perfect building block. No complex conjugations needed here. Just drop it in and wait for the wisdom.

Use it when picking a restaurant with friends. Use it when a coworker finishes a presentation. Use it when you are lost in a giant mall. It works perfectly in text messages too. If you want to sound like a local, say it with a slight tilt of the head. It signals that you are collaborative and not bossy.

Do not use it if you have already made up your mind. That is just baiting people! Avoid it in high-stakes emergencies where you need an order, not a suggestion. Also, do not use it with a very high-ranking boss unless they ask for your input first. In very traditional settings, it might seem like you lack confidence.

Chinese culture often values 'saving face' and group harmony. Asking for a suggestion is a great way to give someone else 'face.' It shows you respect their expertise or taste. It is a 'soft' way to communicate. It avoids the bluntness of making a solo decision that others might dislike.

If you are with best friends, try 推荐一下？ (Recommend something?). In a formal office, use 我想听听您的看法 (I want to hear your view). For a quick text, just 建议呢？ (Suggestions?) works wonders. Each one changes the flavor but keeps the same helpful heart.
