I achieved a big success.

Today is the last day of the month, do you have any special plans?

There is a friend's wedding on the thirtieth of this month.

I turned thirty years old.

I will turn thirty this year.

He can speak thirty languages.

He looked at his side and seemed to remember something.

He is good at making yaramiso.

This chaff is the part that remains after the rice harvest.

He is good at solving math problems, I really think he has good brains.
