it is really quite easy
first, you need to learn the peribahasa's maksud
ten peribahasas in a day will be enough.
Next, you need to see what type of essay u are writting
EXP1: Lawatan ke Kuala Lumpur:
bagai rusa masuk kampung
EXP2:Kebaikan gotong-royong:
berat sama dipikul, ringan sama dijinjing
i hope i can help you
P/S my malay is not so good, so i will mix English and Malay together, sorry for any inconvenience caused
