My Mother's Birthday

My mother is turning (better: turns) 70 years old (< not needed when talking about someone's age) tomorrow. My family and I need to visit her with my family in order to celebrate her birthday.
Typically, (better: Traditionally,) Korean children prepare money certificates for this occasion. It might sound too weird but it is happening that is what we do in Korea.
My credit card has been (better: is) maxed out so I felt pressure to give a lot of money to my mother. By the way, Korean people only(?) celebrate one’s 60th, 70th, 80th, 90th, and 100th birthdays.

My Mother's Birthday

My mother is turning 70 years old tomorrow. My family and I need to visit her in order to celebrate her birthday.

Typical Korean children prepare money certificates for this occasion. It might sound kind of weird but it is happening that is what we do in Korea.
My credit card has been maxed out so I felt pressure (feel reluctant?) to give my mother a lot of money. By the way, Korean people celebrate one’s 60th, 70th, 80th, 90th, and 100th birthday.
