Learn not to review slogans.

Sleepy in spring, sleepy in autumn and sleepy in summer.

Sleepless winter and March

Someone rewrote it in the back.

Ferris Buller's day off.

Summer is just right for sleeping.

Another version is

Spring is not a day to study,

Summer is very hot, just right for sleeping.

Mosquitoes nap in autumn and winter,

Pack your schoolbag and come back next year.

I think it should be these words, so close.
