China stocks slump
中国股市暴跌
Chinese stocks fell sharply on Thursday, posting the second biggest slump so far in 2015.
中国股市28日遭遇重挫，创下年内第2大单日跌幅。
The Shanghai Composite Index fell 6.5%, to 4,620.27.
沪指收报4620.27点，跌幅6.50%；
The Shenzhen Component Index slumped 6.19%, to 15,912.95.
深成指收报15912.95点，跌幅6.19%。

According to Reuters, the stocks fell after a growing number of brokerages tightened requirements on margin financing - an important engine behind a red-hot rally in Chinese share markets.
据路透社分析，越来越多的券商宣布收紧保证金融资，而融资是推动中国股市飙升的重要引擎。
