You're rubbing against the edge of death.

他tā在zài心里xīnli反复fǎnfù思量sīliang这zhè件jiàn事shì。

He turned over the matter in his mind.

反复fǎnfù三sān六liù遍biàn还是háishi没méi查出cháchū个gè所以然suǒyǐrán。

No matter how many times we try, we still can't figure it out.

我wǒ知道zhīdào自己zìjǐ是shì个gè累赘léizhuì，你nǐ没méi必要bìyào反复fǎnfù提tí。

I know I'm a burden; you don't have to repeat it.
