China V-Day Parade: All the weapons seem to be integrated into the vehicles

It seems like it's basically the end of towed weapons systems like artillery right? I did find this reddit post about the same for the US military: https://www.reddit.com/r/Military/comments/1bv7ah6/the_end_of_an_era_us_army_signals_shift_away_from/

It always seemed like towing a weapon would be a huge time-sink. Someone in the comments mentioned that the US military is designed for imperialism (my word) so they need stuff that is lighter-weight to transport on aircraft. So I guess with Chinese systems being actually designed for defense and not having to move them on airplanes, having them on vehicles makes sense.
