It's worth noting that's Long March 11, which is a completely different vehicle to the Long March 5 (the one which will launch China's robotic Mars mission(s)) with the only commonality being that they're both Chinese.
Long March 11 is based on solid rocket motors and is much smaller than Long March 5 (roughly equivalent to a Delta IV Heavy or an expendable Falcon 9) which uses kerosene and oxygen for the first stage and hydrogen and oxygen for the second stage.
