In ancient times, there were four poems about life sadness and four poems about life happiness. What is this?

Four great pleasures in life:

After a long drought,

Meet an old friend in another country;

Wedding night,

When nominating the gold medal.

Four great sorrows in life:

A long drought meets dew-a drop,

Meet an old friend of another country-a creditor;

Wedding night-next door,

When nominating for an Academy Award-Other.
