Cao Cao rides a horse joke

Landlord, you have the wrong number. The original riddle is:

Defending Xuzhou lost most of it (some people say it was "breaking the separation of Xuzhou brothers"), beating Lu Bu to knock off the scarf crown, scolding Cao Cao for riding away (some people say it was "scolding Hou Cheng for stealing flowers and horses"), and hating Dong Zhuo for being heartless.

The answer is: Germany.

Note: Xu's "big loss" means no "profit", but "embarrassment"

"Cloth" typed "towel" as "+"

"Scolding" and removing "horse" is "stubbornness"

Adding up "one" and "heart" is "virtue"
