Nearly completed this puzzle but stuck on 2 clues. 4 Down - Chinese city at the head of the greater Hinggan Range roked by two earthquakes in February/March - I have T?h? and 49 Down - Flaming Machines - I have L?P?O?S Would be grateful for any help, thanks
49d Flaming is an internet term for sending inflammatory messages so I think the answer will be laptops because they could be the machines used to send such messages.
