On the other hand Huawei are the number one telecoms company in the world and Xiaomi, ZTE and others make damned good phones. But then GM didn't almost go bankrupt because they're the best. Their planned obsolescence got the better of them and people stopped buying their rubbish so Japanese cars took over. And, of course, there's Boeing, the perfect example of hubris, stupidity and greed.
Chinese automotive industry is just bad.
If you look at their cars then it's a mix of older western/japanese designs but less reliable.
Scooters and other "simple" designs seem to be working "good enough" though.
Even if it breaks then parts and labour is cheap.
In the field of electric vehicles they are very good.
I mean most of e-scooters or ebikes are pretty much all chinese parts rebranded as western.
Say bafang motors.
Personally I use FiiO E07K, a chinese DAC+amp which had good reviews at the time.
I'm on my second Xiaomi phone.
Also the autonomous vaccum cleaner. Works fine and didn't break down so far.
Had a samsung one which threw errors right after warranty period.
Battery IC most likely failed. Cells were fine (checked by separate equipment).
It should also be noted that western equipment quality is regressing.
Cutting every single penny.
Even damn IC's are regressing.
A lot of classic IC's receive "C" versions which are worse quality.
Lower maximum ratings, worse tolerances.
1980's standard quality parts made today are 10x price.
In the 90's and early 2000's german cars were regarded as impossible to break.
Now I'm watching a VW golf engine throwing a rod before 300k Km (187.5k miles) in a long term road test.
Meanwhile those older ones could get around 500k-1M km.
I have a friend from Belarus who told me of Audi 80 B3 (early 90's/late 80's) which had something like 1.5M km on original engine(it was smoking though).
Test equipment ?
Weller (german) was caught skipping fuses in their new soldering stations.
Optional software upgrade (unlocking true hardware possibilities) making oscilloscope cost 5-10 times more.
The hardware is there, already paid for. It's just software locked.
Rigol had the same thing but "accident" happened and unlock software leaked.
Later rigol gave it to anyone for free.
On my university I did see some chinese test equipment from 1980's.
Analog oscilloscopes were still working fine.
Not sure about internal construction.
Chinese did a lot of copying from the USSR(especially in aerospace and electronic industry) but later also from the west when they gained access.
Personally I use 1980's french scope(excellent serviceablity,almost all chips are socketed) and 1992 Soviet/Lituanian Scope (USSR collapsed in 91).
Along with it 1977 RF generator made in USSR(more crude design but they didn't skip on materials, copper shielding and cast iron frame).
In the field of advanced semicondutors as we can witness the progress was slowing down until AMD started pushing intel.
Chinese and Russians are constantly working on their own designs.
Mainly for military/government use as western equivalents can have backdoors usable by US.
Russians have their Baikal and Elbrus CPU's which are in 28nm process.
Production started in 2015-2016.
And Chinese are pursuing the same route.
US was previously stopping the exports of supercomputer hardware to china so it's logical that they want to be independent by making their own capable chips.
