The Cantonese Ambassador teaches us three idioms related to experiences and feelings. Follow along with the lesson on DIU Pod 56 (starting at the 49:24 mark).
一見鍾情 (jat1 gin3 zung1 cing4)
Love at first sight
一見如故 (jat1 gin3 jyu4 gu3)
A feeling of nostalgia, or knowing someone for a long time (even though you’ve just recently met)
百聞不如一見 (baak3 man4 bat1 jyu4 jat1 gin3)
Seeing is believing. Literal translation: hearing (about something) one hundred times does not equal seeing it once.
