The puerile keyboard warriors' bile is too vile to repeat but it seems to be based on envy, that the Chinese, after generations of deprivation, have shown the world they can compete and are a force to be reckoned with.
The reason why they're locked in an escalating trade war with the Trump administration is that they were better at doing business than the Americans.
No one would countenance China's human rights record but if that was the yardstick for not doing business, then we may as well raise the drawbridge.
But it's not just in this country that the mention of China sends fear into the minds of even the well educated.
Claims by Canterbury University professor Anne-Marie Brady that she was being intimated by the Chinese, having her house and office broken into and her car interfered after researching the Chinese Communist Party's influence in the western world is a case in point. Coverage of her claims swept around the world, academics involved in the same sort of work, called in the security specialists.
Will they now relax after the police here, following a nine-month investigation using the most sophisticated of police resources including detailed forensic analysis and taking expert advice, finding nothing for the Chinese to answer?
The answer is not on your nelly.
China and suspicion go hand in hand, reminiscent in this country of reds under the bed and the dancing Cossack ads of the Muldoon error when it came to the Russians.
One of those keyboard warriors put it all into some sort of perspective though, particularly when it comes to our super spy agency the GCSB rejecting the Chinese telecommunications giant Huawei's involvement in Spark's 5G broadband roll-out.
He said: "So we won't use Huawei equipment because the Americans say it has back doors for spying but presumably they would be fine with us using Cisco made in the USA because its back doors are safe!"
Fortunately my emails aren't anything to go by - hopefully.
