### Chinese: 但也不是规律到能精准预测，大概一周左右的公差，需要提前准备，有时候运气差也会翻车（突然提前好几天）。
### English: But it is not the rule to be able to accurately predict, approximately a week of <v>public transportation</v>, need to be prepared in advance, sometimes the bad luck will turn ( suddenly several days in advance).
### Errors: There is a major accuracy/mistranslation error at "public transportation" within <v></v>.

### Improved English: But it is not so regular that you can precisely predict it; there is a difference of around a week; you need to prepare early and sometimes you may get unlucky and it arrives several days earlier.
