Just flipping through a textbook, I came across a quirky mix-up story:

In a middle-school Chinese language textbook, there was a classical Chinese text called “Feng Wanzhen,” which tells the story of a girl named Feng Wanzhen from Xie Zhuang near the Yuanmingyuan who led others to resist the British army during the Second Opium War.
But 10 years ago, it was removed from the textbook.
Historian Yang Tianshi’s investigation found that it was entirely fictional—there is no such place name, and no such personal name.
The story first appeared in the supplement section of the 1915 “Shenbao,” as a short wuxia novel.
In 1916, it was included in “Qing Ping Lei Chao.” The whole book compiled historical anecdotes, and as a result, people believed it was something that really happened, and it was passed along inaccurately (half true, half false) for nearly a century.
