Here are five simple expressions to say "no" in Chinese with simple examples: 1. 不 (bù) - This is a simple and common way to say "no" in Chinese. It can be used in a variety of contexts and is a general negative word. Example: A: 你喜欢苹果吗？ (nǐ xǐ huān píng guǒ ma?) (Do you like apples?) B: 不 (bù) (No) I normally don’t answer people with just a simple 不 to say no, because it sounds rude. But if you are in a fight with someone, I guess it is a good language tool. 2. 不要 (bù yào) - This phrase means "don't want" or "don't." It can be used to say "no" in a more polite or indirect way. Example: A: 吃蛋糕吗？ (chī dàn gāo ma?) (Do you want to eatcake?) B: 不要，谢谢。 (bù yào, xiè xiè) (No, thank you.) 3. 不行 (bù xíng) - This phrase means "can't" or "not allowed." It can be used to say "no" in a more formal or assertive way. Example: A: 你能给我五块钱吗？ (nǐ néng gěi wǒ wǔ kuài qián ma?) (Can you give me five dollars?) B: 不行，我没有五块钱。 (bù xíng, wǒ méi yǒu wǔ kuài qián) (No, I don't have five dollars.) 5. 不可以 (bù kě yǐ) - This phrase means "cannot" or "not allowed." "不可以" (bù kě yǐ) is often used to indicate that something is not allowed or not permitted. Example: A: 妈妈，我能去朋友家玩吗？ (mā ma, wǒ néng qù péng you jiā wán ma?) (Mom, can I go to my friend's house to play?) B: 不可以，你还没有完成你的作业。 (bù kě yǐ, nǐ hái méi yǒu wán chéng nǐ de zuò yè) (No, you have not finished your homework yet.)
