On the country's largest review site, Douban.com, 10,674 viewers gave it scores that average 7.9 points out of 10.

For many viewers, the series is a reflection of the anxiety and frustration they face because of the Chinese college-entrance exam, or gao-kao, which uses scores as the only criterion for admission.

One viewer, who reviewed the series on Douban.com, says: "The conflict between Duoduo and her mother (who pushes her daughter hard) is what happens in my life. Every time the school releases scores, I feel extremely scared if I fail to meet my mother's expectations."

In the series, three teenagers－from a low-income, a middle-class and a rich family, respectively－face the same dilemma: stay home or go abroad to study.

Dwelling on the subject of sending children abroad to study, chief producer Xu Xiao'ou tells China Daily: "It's not an easy choice. Besides the separation, families also have to endure economic stress, culture shock and language barriers.

"The struggle resonates with Chinese audiences. Most of them see their depression and confusion reflected in the series," Xu says.
