I have read "Luotuo Xiangzi" by Mr. Lao She many times. The ending of the protagonist Xiangzi has always made me sad. I have dreamed of changing Xiangzi's ending countless times, but I know it is impossible. I can only write down those low-level workers who work for people and horses in order to make up for the sadness of reading "Camel Xiangzi"... This book uses Mr. Lao She's "Camel Xiangzi" to travel back to the old Beijing city and reverse the shabby life of the lower class people in the old era...
