Q: “Decision in Process” for 3 weeks during Chinese Winter Holiday/CNY. Should I be worried?

I have an R1 revision submitted to the Journal of Urban Management. Jan 22: Status changed to "Decision in Process". Current Status: It has been stuck there for 3 weeks with no update. I know the Lunar New Year and winter holidays are happening now. Is it standard for this specific journal (JUM) to completely freeze "Decision in Process" papers during this period? I am debating whether to email them or if I should just wait until late February. Is 3 weeks in "Decision" normal for this time of year?
