I think it's more like 50+22 for most DEC. 57+22 is upper level. 27+22 for any competitive FO but 20+14 would be a junior FO. It's less pay than a SO on POS18. No guaranteed flight pay and what I believe is no education allowance.
It's a job for someone who wants a step-up from a SEA LCC and does not realise that the salary would not let you survive with a family in HK unless you all become cup noodle crew.
And that's before spending your days off attending meaningless PCR tests
