Shanghai is really a renowned international town pulling more and more attention from throughout the world; so see what this city provides with hotelbye . Shanghai is a well known travel destination for visitors. In Shanghai you will see the striking Yu Garden (Yù Yuán), also referred to as the Garden of Happiness. This Garden covers an area in excess of 20,000 square yards and consists of an outer and an interior garden. The oldest part may be the Outer Garden with further changes being produced in the 18th century when Sansui Tang, the park's major hall, was added. The newer and significantly smaller Inner Garden dates from 1709 and includes functions typical of a conventional Chinese writer's Garden: desirable little pavilions, ornamental stones, and small pile ranges, dividing walls and little lakes, and a richly furnished theatrical stage.

As with most things that are mfg in China but shipped overseas, what is sold in China - may not be authentic. If you go to a legitimate boutique, even then, it may not be authentic, best to just go with plan to get what you like and if you need brand specific items, Hong Kong is your best bet for authentic items in their specific stores.
