Not really, I am 100% sure that's not the case in China right now. Although many over there are against the war and killing of civilians, they blame it most on US/NATO/Ukraine government instead. That's not hard to see due to the following reasons:
- US/West are their biggest enemy, Russian are their friendly neighbour. They believe US is by far the biggest terrorist in the world, with the killing of most civilians over past decades or so (from their invasion on numerous countries). And they believe if Russian is fallen, it would be their turn to be surrounded by threat of NATO (their enemies) in future.
- They hate western intervention/propaganda on numerous issues against them over the years: Taiwan sovereignty, Hong Kong protest, Xinjiang cotton, Trade war
- Their current popular view is, US/NATO/Ukraine Neo-Nazi are the cause of the conflict as it present a big threat to safety of Russian people, and Ukraine government/soldiers are the ones who are committing those war crimes.
- They idolise Putin, probably more than Russian people do.
- China is essentially socialist country run by communist party, they are very happy with their government, and hate any western intervention/propaganda against them. Their rise of economical power in recent years/decade, and relative success over controlling breakout of COVID in their country, further reinforce their faith on their own government, rather than the west.
