One day in London

I went to London yestoday. That's capital of British which city full of modern building in the UK.
I feel London is more better than Leicester,but both of them have advantages.Leicester is fit for life and go on holiday.And London is a best finance city,so people have more work's chice.
When I walk in London's street I believe that developed countries have more things are developing countries should study.So we must work hard,then,everywhere wo can find good jobs
