Sigh.

New wheel bearings, new problem. The wong wong sound between 60-80km/h has disappeared completely, but now after some time of driving, the bearings will exhibit a high pitch noise/wheee noise below 40km/h. I was told by the experts that the noise is common with some NTN bearings, and should disappear after enough mileage has been racked up.

spareparts shops selling Proton ATF is it original? worry if its imitation.
If you're worried, buy it from an authorised Proton dealer. I dunno how to differentiate original and fake ATF.

I feel my persona's steering and car vibrating when speed up to 130-140 and become not vibrating after 150.
Why is it like this?
Thanks.
Tyre not completely round / absorber mounting rosak / rim problem.
Go check your absorber mountings, and if they are spoilt, change them, then only re-do the balancing. Do high speed balancing if needed.
