This paper discusses the price and wage movement during Kang Hsi (康熙) to Cha Qin (嘉慶 )years of the Ching Dynasty (1662-1820).Results showed that within those years, prices went up 2 to 4 times. As for specific groups of products, prices of those of basic necessities, such as rice, increased the most (more than 4 times), while of luxury goods, increased the leat (about 2 times). It meant that the pressure of inflation had the biggest pressure on the poor while the effects on the rich were little.Compared to price increases, wage did not chang much during the same period. Poor people still got paid more or less the same while the cosrt of basic necessities increaed 4-fold. Thus the plight of the poor could be seen. This was the main reason why the strength of the Ching Dynsty turned weak and society became unstable.
