传道书 4:8

有人孤单无二，无子无兄，竟劳碌不息，眼目也不以钱财为足。他说：「我劳劳碌碌，刻苦自己，不享福乐，到底是为谁呢？」这也是虚空，是极重的劳苦。

yǒu rén gū dān wú èr ， wú zǐ wú xiōng ， jìng láo lù bù xī ， yǎn mù yě bù yǐ qián cái wèi zú 。 tā shuō ：「 wǒ láo láo lù lù ， kè kǔ zì jǐ ， bù xiǎng fú lè ， dào dǐ shì wèi shuí ne ？」 zhè yě shì xū kōng ， shì jí zhòng de láo kǔ 。

There is one who is alone, and he has neither son nor brother. There is no end to all of his labor, neither are his eyes satisfied with wealth. “For whom then do I labor and deprive my soul of enjoyment?” This also is vanity. Yes, it is a miserable business.
