Zhang Yu didn't respond to everyone's sudden attempts to get close again.
She was busy preparing things for Zhang Li's study abroad, and the most urgent issue was, "After going abroad, you'll need to speak English. Xiao Li, how's your English proficiency?"
Many Chinese people abroad migrated before the liberation, and it's uncertain what they think of students from the homeland.
More importantly, after you arrive abroad, foreigners might trick you, but the so-called fellow townsfolk might even more likely trick you.
If possible, Zhang Yu hoped that Zhang Li could keep her distance from these so-called fellow townsfolk, but she found it hard to express this directly.
As someone who has never been abroad, how would she know that the so-called fellow townsfolk are particularly deceptive; she could only remind Zhang Li to be extra cautious.
"Overseas, even if someone calls you 'fellow townsfolk,' you must not let your guard down."
