Ahahah...i wonder myself. Lol
On a serious note though, deflation is indeed a bad thing for China or any other country for that matter especially if its sustained for a long period of time. China needs to find way to get out of this sustained deflation loop, where most companies believe they can only compete or stay relevant by lowering prices by as much as possible even to the point of eating into the little profits they made. Its not sustainable and has other multiplier effects on consumption and productivity.
Deflation is a bad thing for a mature Western economy dependent on consumption on wealthy consumers to power growth.
But China is a developing country with less wealthy consumers that consume things on massive volumes once an affordable price point is met. In order for Chinese to consume as much as the developed world then the consumerables by necessity needs to be cheaper and the profits lower.
For things like HSR, EVs, high definition TVs, etc. Chinese people can and do consume more than the West because the price points are pushed lower and lower.
Then on top of that you have a threat of embargo from developed world which are meant to cut you off from products they produce and that they think you can't. In such a scenario, you need to push production in as many fields as you can. And that production will create some deflation.
For a developing country like China the problem had ALWAYS been inflation. No country fell because goods became too cheap and plentiful but many have fallen because they needed a wheelbarrow of currency to buy a loaf of bread or needed to wait in line for a bar of soap.
China has more and cheaper goods in nearly every category and gaining a share in the few that they haven't collapsed the price yet. Deflation, in my opinion, is about as real a problem as the cries about "overcapacity" in Chinese chips production when they have an embargo on China for chips.
Fuck them and full speed ahead. The pricing will work itself out as China's economy matures.
