A blessing in disguise never knows which book is a blessing in disguise.

A blessing in disguise is a blessing in disguise. It is selected from Huainan Lie Hong.

Lie Hong in Huainan was written by Liu An, the king of Huainan in the Western Han Dynasty. An allusion in the article later came from the idiom "A blessing in disguise is a blessing in disguise".

"A blessing in disguise is a blessing in disguise" means that under certain conditions, fortunes can be transformed into each other, and everything has two sides.
