Well, I am aware it is not a common knowledge. But thats the doctrine of PLA at that time when they designed Type 95 that in emergency situation (China under land attack) that Chinese rifle could fire NATO 5.56 and not the other way around
I'm not saying that "it's not common knowledge".
I'm saying that you are making spectacular claims as if it was common knowledge.
That is to say, I am trying to politely say that your original claim was questionable to begin with, and instead of talking about it as if it were true, you should have asked whether it was true to begin with.
If other people are dog piling you on this, it is because the sheer audacity of the claim and question was so ridiculous to begin with.
Now that you understand that your original claim and belief was false and untrue, then that is all that matters. After all, it's fine to make honest mistakes.
