This supporting character was a country bumpkin who couldn’t get married due to her obesity. According to the original script, this country girl Qiao Mei was a fatty spoiled by her grandfather. However, their relatives were all vicious and cruel people. Her grandfather had poor health, so once he died, the relatives would divide and swallow up his assets.
