I learned new word -“ strike up “from the Chapter 15 Of “The Third Ear” recently .

Original sentence：
We struck up a conversation in Chinese, and the banter began.

“Strike up“ means “to start a relationship or conversation with someone “

I try to practice making up sentences :
1. Amy is a talkative person and it is easy to strike up a conversation with friends that she just met.
2. Alan struck up a friendship with a beautiful girl at my birthday party last month.
3. She was too shy to strike up a conversation with him.
