损人利己

qiān wàn bù kě zuò rèn hé sǔn rén lì jǐ de shì

千万不可作任何损人利己的事。

Never do anything to your profit at another's expense.

duì wǒ lái shuō zhè sì hū zhǐ shì yī zhǒng shāng pǐn jiāo huàn shuāng fāng dōu xiǎng sǔn rén lì jǐ

对我来说，这似乎只是一种商品交换，双方都想损人利己。

To me it would seem only a commercial exchange, in which each wished to be benefited at the expense of the other.
