Chang'an Avenue, as the main road for the parade, has been decorated with flower beds together with patterns and light installations set along the route.

Temporary stands for spectators were installed on the sides of Chang'an Avenue on Aug 18.

There are 129 public toilets with 2,390 seats around Tian'anmen Square with many mobile toilets installed in preparation for the parade. About 24 people will share each seat based on the estimated number of visitors on parade day.

Some 58 main roads on or near the parade route will be cleaned and 22 cleaning vehicles will tidy the main road on Sept 3 to reduce dust after the parade has passed by.

National flags have been hung on all buildings in downtown Beijing from Sept 1 to 5 to commemorate the 70th anniversary of the end of World War II.
