1930 how much ocean is an acre of land in Nanjing?

Two oceans. According to the query of "polished rice", the purchasing power of Yiyang was relatively strong during the Republic of China. According to "polished rice", two oceans can buy an acre of land. I saw an old title deed in Daxing, Beijing, saying it was October of the Republic of China. A tenant surnamed Liu in Daxing Kangying Village bought four acres of three-point land from the landlord and spent only seven yuan. In other words, one acre of land is not worth two oceans.
