Pushing one's troubles onto others like this is despicable.
Tips
history
Recorded in 《史记·赵世家》 (Records of the Grand Historian, Zhao section): 韩国不愿入秦,是想把祸事转嫁给赵国 — Han didn't want to surrender to Qin because it wanted to dump the disaster on Zhao instead.
memory
嫁 literally means 'to marry off' — picture marrying off your misfortune (祸) to someone else (于人) so it becomes their problem.
