                                                     Like a Heaven on Earth

     Many cities have slogans (宣传标语) to attract you to visit and spend your tourist money. These are

usually written by a travel agency, and no matter how clever or well thought out, they often fall on the deaf ears of experienced travelers. But there are proverbs that are time-tested-like this one, which translates

to: Up in the sky there is heaven, down on earth there is Suzhou and Hangzhou.

     That's a pretty bold declaration (宣言) when you consider the size of China and the many beautiful

places to see within its borders. Yet, Suzhou's beauty has won it boasting (自夸) rights.

     Suzhou, built in 514 BC, has a storied past. Marco Polo spent time there in 1276 while on the Silk

Road. Sun Tzu wrote The Art of War in Suzhou when it was the kingdom of Wu.

     While famous for its gardens, Suzhou has long been inspirational to artists, musicians and craftsmen.

There is far more to Suzhou than its gardens - respect for art, just for starters.

     There is a peaceful air that reflects the spirit of the area. You can see that it is a city trying to remain

very livable and keep its beauty even as it grows.

      Perhaps it's the smiles you see on the streets, or maybe the way they take care of the elderly in the

city. Maybe it is the way they promote art and culture as the government provides studio space for artists

to work on their traditional skills - or it could be that there are pockets of beauty all over the city.

       You don't have to go far to find one of these to escape the honking horns (汽车喇叭响) or the

electric bikes, and find your own little piece of Heaven on Earth.
