I want to know the answer to the following question:
What city was massacred for not wearing the proper haircut?
All the background I'm provided with is that "Li Chengdong, a Han Chinese general who had served the Ming but surrendered to the Qing, ordered his Han troops to carry out three separate massacres in the city of Jiading within a month, resulting in tens of thousands of deaths.". Is that enough to answer the question?
