He didn't know where Madam Chen got so much confidence from, thinking her grandchildren could both win awards, after all, not every kid can be as smart as Xu Mumu.
Regarding those siblings from back home participating in the competition, Xu Mumu sent the materials back but didn't pay much attention afterwards, worried that calling them from time to time would add pressure to their competition.
Unfortunately, Madam Chen didn't think this way. Despite the expensive phone bills, she called without fail every day to supervise her grandchildren's studies.
Xu Minglei felt like he was living in a world of suffering; he thought that his grandma knew even more about the competition than he did. If she could speak English, she might have gone to compete herself, just for the prize money.
Especially since, after a couple of phone calls, Li Caixia and the others knew there might be prize money for winning, they also joined in the supervision squad.
