how do you say close the lid in chinese reddit

The most natural way to say “close the lid” in Chinese is:

• 把盖子盖上。
  Pinyin: bǎ gài zi gài shàng
  Meaning: “Close the lid” (general, for any kind of lid).

If you specifically mean a toilet lid (which is what people on Reddit often ask about), you can say:

• 把马桶盖盖上。
  Pinyin: bǎ mǎ tǒng gài gài shàng
  Meaning: “Close the toilet lid.”

For something like a box or container lid in a casual context, you’ll commonly hear:

• 把盒盖盖上。 (bǎ hé gài gài shàng) – “Close the box lid.”
• 把锅盖盖上。 (bǎ guō gài gài shàng) – “Put the pot lid back on / close the pot lid.”

A tiny “story-style” example of how it looks in a conversation:

你用完了记得把盖子盖上 。
After you use it, remember to close the lid.

These are all natural, everyday phrases a native speaker would understand immediately.
