Have completed this but am puzzled by 3 of of the clues - 10 down (7) prejudices Chinese response which blocks plonkers. The only possible answer is biasses - unusual spelling which Chambers gives but I dont get the word playditto 18 down (8) left sibling overwhelmed by familiar lie FAL-SIS-M and 27 across (6) very much concerned with afternoon meal - I have gone for the last word and have FARINA but again I dont get it and am not sure if this is right as I had ?ARINA! Can any of my usual mentors assist me please
bi = "In traditional Chinese medicine, one of five responses (bi syndromes) that present as blockages in the circulation of chi in the meridians" so BI + ASSES (plonkers)
