In the beginning of this century, she was born in a small remote village inhabited by the Mongol and Han nationalities. In those years her mother bound her childish feet tightly, using strips of cloth, so her feet remained small and pointed. Although I didn’t know much about life when I was a child, I often felt constrained at the sight of my grandmother’s bound feet. While I was growing up, I read some books about women’s emancipation and started to be more concerned about the fate of women. Chinese women have struggled up a展开更多

The third round of national stockpiling ended on March 28 with both quantity and price higher than the second round. Thus, it supports the price rising of most rare earth products. Especially price of cerium oxide increased by 10.10% month-on-month, leading the rare earth market.展开更多
Rare earth market changes the upward trend recently and began to shock. Price of didymium oxide has fallen from the previous high of 510,000 yuan/ton to 460,000 yuan/ton on Sep. 28.

Price of didymium oxide has fallen from the previous high of 510,000 yuan/ton to 460,000 yuan/ton on Sep. 28. Besides the rational revise of the former price surging, the other reason for the price drop is the slack demand from downstream industries. However, the rare earth groups began cease production to guarantee the market price recently. This is definitely good news for it can ease the oversupply recently. But, whether rare earth price can be backed is finally decided by the demand from downstream industries.展开更多
