This book reflects the three-day massacre of the ancient city of Xuanyang in the 18th year of Kangxi's reign, which resulted in more than nine months of destruction, more than 70 years of desolation, more than 100 years of literary inquisition, and more than 260 years of immigration history. For the first time, the mystery of the annihilation of the ancient city was revealed; for the first time, the immigration ecology of Lizhou was reflected.
