BEIJING, Dec. 29 -- Nearly 30 antiques are on display this week in Beijing's Summer Palace for the first time in more than six decades.

These antiques are part of an exhibition, which opened Monday and will run for two months, showcasing 73 pieces including bronze ware, ceramics, paintings, calligraphy and furniture, as well as historical records. These treasures were hidden from the Japanese invaders during the World War II.

In total, 2,445 antiques from the Summer Palace(Yiheyuan) were packed into 650 cartons and sent to southern China starting in 1933, four years before Japanese invaders seized control of Beijing.

After China won the War of Resistance Against Japanese Aggression in 1945, these treasures were transferred to Nanjing. Many pieces were transferred to the Forbidden City in Beijing, including thousands originally from the Summer Palace.

A total of 368 pieces, mostly ceramics, jade, bronze ware and furniture, were returned to the Summer Palace in the 1950s.
