独生子女

wǒ de péng you shì jiā li de dú shēng zǐ nǚ

我的朋友是家里的独生子女。

My friend was the only child in her family.

dú shēng zǐ nǚ zài dú chǔ shí wǎng wǎng zuì zì zai

独生子女在独处时往往最自在。

The only child is often most comfortable when alone.

总之，独生子女政策已经过时了。

All in all, one child policy has been out of date.
