HO will be flying to HEL 3x weekly during the winter season, instead of 7x weekly. However, the schedule may change if the airline begins the rumored 4x weekly PVG-HEL-MAN service.
Do you happen to have a source for the HEL-MAN rumour ? And is there any hope it'll be a fifth freedom route ?
The airline has not given any information about this. However, someone mentioned this at a.net saying HO wants to serve MAN (via HEL) instead after not getting permits to fly PVG–LHR, which sounds possible to me. Furthermore, this is said by Airlineroute
The CAAC earlier this week updated its route application posting for Juneyao Airlines, now showing Shanghai Pu Dong – Manchester from Nov 2019 [previously shown as Shanghai Pu Dong – Helsinki], exercising 5th freedom rights. This particular one is categorized under "Finland". Expect possible clarification in the next few weeks
So, it's possible that HO will be flying between HEL and MAN using 5th freedom rights
As MAN is intended to be served 4x weekly (which is appears at CAAC) and HEL 3x weekly (7x altogether) during the winter season, HO may plan to serve MAN either non-stop from PVG or via HEL (thus HEL would be daily again).

The word "Quawer" means nothing but it looks great.
