In Mandarin Chinese to say “no, not, don’t” there is simply one word or character: bù （不). In this situation bù uses the fourth tone but sometimes uses the second rising tone.


To make a negative sentence the word order is Subject + bù + Verb + Object.  “I don’t eat food” you would literally say “I not eat food”, or wǒ bù chīfàn （我不吃饭).
