I know there are thousands of chengyu (成语) (4 character proverbs in Chinese) out there, so obviously I would not have time to learn them all.
Could I have 5 of these chengyu from you? (bonus marks if you could explain the meaning/context).
I appreciate it!
An example of a useful Chengyu phrase is one which forms basis of everyday applications: 四通八達 (extend equally in all directions) for example, is sort of where the 八達通 (octopus card in Hong Kong) got its name from.
