I just read that Rainie left EMI for Sun Entertainment in 2017, and this year she came back to EMI
She's "the mastermind" of her new album and has worked with many different producers this time.
In 2020 she will also celebrate her 20th anniversary !
EDIT: Rainie's title song is called 节日快乐 Happy Holiday. It will be released around November 11th, Singles' Day.
The new album will contain nine new songs by nine different producers and creators.
