The Indian exercise was at 4000m+ in Ladakh whilst the PLA one was in the middle of a city in the lowlands with I guess plenty of road access. Also we don't know how long it took to complete the bridge in each case. I expect the Indian army could build a bridge as long as the PLA one, given sufficient time and equipment.
Another handy hint the Russians (re)learned to their cost - never underestimate your opponent.
In what universe has the PLA or even most of us here, myself included that underestimate IA when it's actually the opposite. You want proof? Read, watch, any of the IA retired general officers and almost all will tell anyone willing to listen that Indian military is ahead of the PLA not only in qualitative training, doctrine, bravery, tactical acumen, equipment etc..not to mention if you wade into any pro-Indian defense forums the level of jai Hind and China racist bashing is next level. So I don't get where you're coming at, and if am being blunt here, you're response is actually quite irritating and annoying to be exact.
Like, what's your angle here in the first place? Are you trying to contend that IA is better than the PLA on what area, be specific, since you seem to give the IA claims beyond more than a benefit of the doubt despite their history replete of boasting and chest thumping.
Lastly, China ain't Russia, and Taiwan isn't Ukraine. The only way Taiwan and Ukraine is comparable in some meaningful sense is that both are being used as geopolitical tools/weapons to enrage and goad a violent reaction from Russia with their current so-called special operations a.k.a. Invasion of Ukraine, while the other has been poking, trolling China to force it's hands in armed reunification with Taiwan. Ukraine is a sovereign state, while Taiwan isn't unless you're also one of this persistent westerners who love to insist otherwise international law be damned.
