短语playing with fire和汉语中的玩火自焚意思是对等的，换句话说就是冒险，自找毁灭。
- Climbing that mountain in this bad weather is playing with fire.
- He was playing with fire when he swam across that river at night!
值得注意的是，另一个同火相关的短语，add fuel to the fire 也有对应的汉语成语，即火上浇油。
- John’s poor excuse for being late just added fuel to the fire. Jane was furious.
