     Pavilion of Prince Teng Preface 

【 author 】 Wang Bo  【 Dynasty 】

Tengwang's Pavilion is near the river , Pei Yu Ming Luan stops singing and dancing .

Huadong faces Nanpu cloud , In the dusk of the Pearl curtain, the rain of the Western Hills rolls .

The shadow of the idle cloud pool is long , Things change for a few autumn .

Where is the emperor in the pavilion now ？ Outside the sill, the Yangtze River flows by itself .
