before:
-they used to bycycle and motobycle to go to the company,go shopping,take their children to the school,they also use the public transport like:bus to save money,they usually walk in the close distance
nowaday:
their lifestyle become better,they use car to move instead of bycycle,i rarely see them get bycyle to move in the street
using a lot of car make the environment polluted,causing traffic jam
