This ad featuring Li Yuchun (李宇春) is all over Shanghai right now:
On first glance, the Chinese in this ad is pretty simple, but doesn’t seem to make sense. 我爱你 means “I love you,” and 无所谓 means “don’t care.” Huh?
But look closer… It’s not 无所谓 in the ad, but 无所畏. The final character is different. So the meaning goes from “to not care” to “to have no fear.” The ad intentionally plays with you to draw you in; 无所畏 (“to have no fear”) is not a phrase you normally use in spoken language (although 无所畏 and 无畏 are not so hard to find online).
This ad featuring Han Han part of the same series:
Here you have the same 谓/畏 wordplay, this time introducing the phrase 正能量, a phrase popular among the kids which can’t be translated literally, and is used to mean something like “positive attitude.”
