Question: Do you have any plan to buy a house in this city ?  Absolutely we need a house here . But what makes me upset is the prices in this city .  Our monthly salary can not buy one square meter of the house here .  It is depressing to hear the price goes higher and higher .  More and more people need to buy houses , but the market can not meet the needs , so this caused the bubble in real estate industry .  And the rich still wants to buy more , even though they have at least one house to live .  Have you watched the TV series , Humble Abode ?  Yes , it displays some social problems and interprets the values of our white-collars .  I really , really want a house , even though it is small like a snail house . 

Answer: No
