HS was trying to help me visualise the taste of Yam mooncake which I have never tasted before. Thanks a lot, HS! Here's a thought, taste and memory actually blends well together. If you ever have to try to cram some notes that are just gibberish after many attempts of memorizing them, do so with the help of strong-tasting tidbits. Not that it's the only viable method or even short cut, actual studying effort is still very much required, ok? Besides, full understanding on the topic you're studying in order to retain the information is far more effective than just stamping the material in your head.
