Write the main content of the poem, not less than 12 lines.

Once upon a time there was a Robinson,

Like sailing and adventure.

A trip to South America,

Wandering on an uninhabited desert island.

After many hardships,

Settle down and live a lonely life.

Animal husbandry, fishing and hunting,

Planting wheat is rewarding.

Unexpectedly, Friday came,

Good servant, good helper.

Finally boarded an English ship,

It's hard to be happy when a family is reunited.

(I wrote it myself)
