price inflation

Recently,A lot of food risen price.It is influencing our life.The instant noodles rising 20%-40%.The pig's price rising 60%.The oil ,the soja,and so on.
I don't know why the commodities inflation so fast? Maybe the government should strengthen control the price,and insure the low-income people's normal life. I'm pay attention to the development of the real estate price.Because I don't have my own housing in Suzhou.The government predict the drop in real estate price,but it is just on the opperist part.The real estate price keeps crazy.I still believe the government's predict and I will own a house one day.
