Q: Why are the microphone receivers in Chinese cell phones so poor?
we always hear about how China's cellphone industry is so large and strong, how it makes good cellphones. However, if this is true, it makes little sense why the receiver is of such poor quality. I don't understand. I feel bad for Chinese people who buy these phones and are forced to yell into them because they are of such poor quality.

I'll give you 3 answers to this. Make your pick which you think is most likely
A) In a more technical explanation. High end phones have several microphones, e.g. one by the mouth and one on the top. The two microphones will then both listen. Then to filter out background noise, the sound picked up from both gets compared, a processor determines the difference in direction of the sound based on the speed of sound and can thus filter off the background noise from the mouth facing microphone. Doing this requires processing power and higher end hardware. Generally a lot of China phones are cheap because they are using reference hardware design living up to the bare minimum of what is required.
B) The phones are fine, the people are faulty.
C) All the development budget was put into making a speaker that would be able to play ringtones at a volume where you don't have to be bothered if you are standing behind a jet engine.

+1 for lack of noise cancelation technology.
However, local people always seem to yell into their phones, even if its a Samsung or Apple. Maybe while they grow up all the years of spring festival fireworks permanently damages their hearing by adulthood thus causes the back and forth yelling.
Scandinavian:
people are generally talking very loud, whenever the MIL is visiting our home, I will always talk extra softly to make a point it is possible to communicate without yelling.
My first Samsung Galaxy phone had an issue using a specific headset. Microphone pickup with that particular headset was particularly bad. It was possible to fiddle with hidden settings and fix this. And there are some settings that sets the output volume of the microphone, meaning, yelling will make the phone lower the volume and talking low will boost the volume.
