Today's Chinese word of the day is 右 which means right (the direction, not the opposite of wrong).
In Mandarin 右 is pronounced Yòu.
在右邊 Zài Yòubiān means on the right.
Now if you are on your friend's right in the dark...
我在你的右邊 Wǒ zài nǐ de Yòubiān - I'm on your right. Unless of course you aren't... in which case go read yesterday's word again.
