Two streams of tears. A meme from the 2019 sci-fi film The Wandering Earth. Every time the main character puts his ID card in the truck, a PSA message will automatically play as its computer systems boots up. It goes like this, "Beijing No.3 Transportation Division reminds you: routes are countless, safety is foremost. Unregulated driving leads to loved ones in tears. (lit. loved ones two streams of tears)" This line is oddly catchy despite not even rhyming, and soon caught the attention of many viewers. Now, it is the most quoted line in the entire film.
