In the past seven years, China’s real estate（房地产）industry has developed in a record high speed. For those who earn less but are eager to own a decent and comfortable place of their own in a big city, the high housing price is a heavy burden that they cannot afford. For this reason, the government has taken a series of measures to prevent the housing price from rising too fast, including raising interest rates（利率）and increasing taxes on real estate（房产税）etc. Presently, these measures have achieved initial effects in some cities.
