Cheng Su hung up the phone, feeling a bit puzzled, and thought Qi Taiguo's call was a bit odd this time, he even told her to be careful when going out.
"Was it Taiguo calling?" Mother Cheng asked while beating the egg.
Cheng Su said it was.
"What did he say?"
"Not much, just some casual conversation," Cheng Su smiled and replied.
Mother Cheng then said, "It's easier to stay in touch now; even though he's gone so far away, with this telephone, he can call back to talk, it feels like he's not that far. Back then, we didn't have such things, we had to rely on letters, and they might not even be received."
"That's right. In the future, it will be even more convenient; you can use a mobile phone to speak face-to-face, you can see the person!" Cheng Su laughed.
"Really?" Mother Cheng was surprised and looked at her in wonder: "How do you know there will be?"
"Oh, I saw people abroad doing it," Cheng Su lied without blushing.
