Any views on HKEX 2823, 2828 or 3169 on FSMOne RSP?

I have been RSP-ing 3169 too, but recently I sold it because it will be delisted from HKEX. See below announcement from HKEX
https://www.hkex.com.hk/-/media/HKEX-Market/Ser...

All 3 ETFs track different China indices. Vanguard 3169 is the newest among the 3 ETFs, about 3 years old. I used FSM ETF Chart Centre to compare the performance of the 3 ETFs:

Based on this 2-year performance comparison chart, it seems to be 3169 2823 2828 from best to worst. Both 3169 2823 move quite close to each other, but 2828 not recovering so well from March low last year.

Do take note that this is past performance, and it may not represent future performance.
