Shanghai authorities are planning to convert a riverside park in Baoshan district into a theme park to commemorate the Battle of Songhu in 1937.

The three-month battle between Chinese and Japanese troops began Aug 13, 1937, and took place in downtown Shanghai as well as in outlying towns and the beaches of Jiangsu province.

The battle eventually escalated into a full-scale war waged by Japan that would involve China's major regions.
