Xi has also been campaigning on institutional reforms but the string of abrupt and sometimes insufficiently vetted policies showed Xi's success on this front had been limited. Some may even attribute the policy mishaps to Xi's overpoliticization of the bureaucracy.
You show your lack of knowledge here. Xi actually tried really hard to make reforms in 2015 and he faced such a huge wall of resistance by interest groups, local governments, corruption, bureaucracy etc that ultimately he had to make a tactical retreat.
Since then he has been slowly but steadily chipping away power from these interest groups while also cleansing the Party and the government from corruption. You realise that his anti-corruption campaign has been transformed to a proper institutionalised work, right?
The big change for Xi came in the 19th Party Congress where he finally gained much more power than he had before. Even then though, he still faced many issues and resistance from entrenched interest groups. However, he also made many economic/tech/political changes and reforms that he (hopefully) gained the trust of the Party to elect him for a 3rd term this year.
Your anger to Xi because (i assume) the HK market went down (btw it just went up today lol) doesn't make sense. China makes decisions based on the real economy, not based on what stocks the computer algorithms decide to sell or not.
As for Ukraine, as I said, the war is still early. For China, there are positives and negatives. We will have to wait to see if the positives will outweigh the negatives. So far IMO things are going ok
