As is known to us,China has the biggest population in the
world,which is more than 1,300,000,000.Such a large population causes
some problems in cities,that's the unemployment.Too many people gather
in cities and the jobs are not enough.Some graduates can't find a job
though they have left school for years.In addition,traffic jam is
another problem resulting from the big population.There are too many
cars on the roads and streets. The situation of the countryside is not
good.Too many people live in the countryside and we don't have enough
farm land for them. Fortunately,our government has realized the
problems and has attached great importance to them.
