Lu Xun sculpture and tai chi sword
Tai chi swords do not actually look like cutlasses, that is just blurriness.
Lu Xun's tomb is right around here (according to the sign nearby, not pictured). It was established as a national cultural landmark in 1961 (the 80th anniversary of Lu's birth) by Mao. This park itself already existed before (it was called Hongkou Park, since it's in Hongkou district), but was turned into Lu Xun Park in 1959 with a big ceremony and stuff (as far as I could tell from the video in the museum).
