Eastern people’s side welcoming different temperatures (6)
I believe the answer is:
manchu
'eastern people's side welcoming different temperatures' is the definition.
I can't judge whether this defines the answer.
'side welcoming different temperatures' is the wordplay.
'side' becomes 'Man U' (Manchester United, footballing side).
'welcoming' means one lot of letters goes inside another (in sense of 'inviting in').
'different temperatures' becomes 'ch' (I can't justify this - if you can you should give a lot more credence to this answer).
'manu' going around 'ch' is 'MANCHU'.
Can you help me to learn more?
(Other definitions for manchu that I've seen before include "Last imperial dynasty of China" , "old language" , "Asian language" , "Last Chinese imperial dynasty" , "Member of Chinese family" .)
