"聽不懂", as my fellow foreigners in Taiwan will know, is one of the most useful Chinese phrases to know.
Here's a mini-lesson for you:
聽: hear
不: no
懂: understand
So, basically... "I hear you speaking to me, but I have no idea what you're saying."
Highly useful for those of you who, like me, have no clue what anyone is saying to you at any given moment in time.
This (kinda painstakingly) handwritten sticker is set against a teal background and printed on a high-quality vinyl sticker paper, then finished with a glossy protective overlay.
聽不懂 "Ting Bu Dong" (I Don't Understand) Vinyl Sticker
Material: Vinyl
Finish: Glossy
Dimensions: Approx. 9cm x 4.5cm
These stickers are printed on high-quality vinyl sticker paper and covered with an extra protective overlay, making them resistant to water, weather, and sun. (I don't necessarily recommend putting them through the dishwasher, though, because I don't have a dishwasher so I don't actually know if they would survive that ordeal.)
