Words on the top is a word pun on rice. It is written in the character that means "rice", but pronunciation-wise, it means "doing something you know is wrong".
The words in the circles (right to left) is an elegant sequence of words that mean "Simple tea and rice is enough for me." One of the words in them can mean "poop".
On the bottom, it is again another pun. The pronunciation of the Chinese word of "die" is similar to that of "poop", and so I said "Can't let go even if it's death/poop.".
