One could criticize the Chinese regulator on the grounds that the effect of its moves to increase margin requirements did not last long; or one could criticize it on the grounds that its moves caused the recent crash. But, either way, these measures were intended to stem the rise in market prices, rather than to contribute to it.
你可以批评中国监管者他们提高保证金要求的动作的效果没有维持多少时间，你也可以批评他们的动作导致了最近的崩盘。但是，无论如何，这些措施是为了阻止市场价格的攀升，而不是促使它们攀升。
