The ¥

Over-investment and excess capacity depends on China’s economy. Fearing inflation, authorities see that the deflating housing market will limit fiscal stimulus. Many fear of inflation. Major export countries like the US and Europe, has been slow in growth, and as Europe debt crisis continues, it would stunt the growth of China's growth.
With China's capital account closed, many could not see any significant changes with the economy, which allows money can now flow out of the economy more easily than before. Late 2011, China’s surplus in the trade of goods, services and transfers, was offset by outflows from the capital account, which makes many investors insecure with the state of the economy.
China’s bank sells the yuan at a below-market rate, having it set the exchange rate above the market value and sell foreign reserves to support the yuan. China’s foreign-exchange reserves declined, which the central bank was trying to hold up the value of the currency as a reaction to the declining. Foreign-exchange in-flows resumed recently, but that the growth has been slow.
The Chinese are protecting their money by holding less yuan and/or gamble. Gambling is used as an currency converter, where one can change from Yuan to US dollars, or as a way to store and/or hold money. With the increase of gambling recently in China, it maybe a sign where the Chinese economy would get better soon.
Even though the economy has been in a slow growth period, it has not collapsed, and there is still time and new variables that would warn people if it does.
