"Dragon Force: So Long, Ultraman" shown in China

The alleged rip off film of the original Ultraman TV show "Dragon Force: So Long, Ultraman" already shown in China. And their 1st 3 days of box office gross scored over 16 Million Chinese Yuan/270 Million Japanese Yen (that's a typical box office gross of a Sentai/Kamen Rider movie).
