In Chinese, "作死" (zuò sǐ) means "to act recklessly or do something stupid that could lead to one's own death." This phrase comes from a combination of the characters "作" (zuò), which means "to do," and "死" (sǐ), which means "death."

In English, this concept could be translated as "to court death" or "to tempt fate." Here are some example sentences in English and their translations in Chinese:

He was drunk and decided to drive home, but he crashed his car and died. 他喝醉了，决定开车回家，但他撞车死了。

She went bungee jumping without checking the equipment, and it broke. 她去蹦极没有检查过器材，结果断了。

He climbed up the side of a tall building without any safety gear. 他没有任何安全设备爬上了一座高楼。

In these examples, the individuals are engaging in risky behavior that could potentially lead to their own deaths. In Chinese, this behavior could be described as "zuò sǐ."
