The literal translation of please would be 请 (qing3). See these examples:
- 回家时,请先去超市买牛奶
- Huí jiā shí, qǐng xiān qù chāo shì mǎi niú nǎi
- When you come home, please first go to the market to buy some milk.
- 请帮一下我的忙
- Qǐng bāng yī xià wǒ de máng
- Please do me a favor
How do you say Blue in Chinese?
How do you say Good Morning in Chinese?
In fact ,we don’t use please when we talk to a person we are familiar with, because it will make the person feeling we are not in good relationship .
and “请帮一下我的忙” ,we never express ourselves like that , we usually say qing bang ge mang or bang ge mang (帮个忙),or 麻烦帮个忙(ma fan bang ge mang) etc.
