Scientific minds and romantic hearts

Scientific researchers are usually stereotyped as nerds with low EQ. In the case of the twin bothers, the stereotype couldn't be further from the truth.

Besides Chinese calligraphy and painting, they also like popular songs and American TV series. One of Yue's new year resolutions is to learn guitar and play one song for his girlfriend, and Chao hopes he can find his true love in this Lunar New Year.

Traditional values such as filial piety also mean a lot to the two scientific minds. Every year when they go back to hometown, they bring parents gifts like local food of Beijing and Nanjing, and sometimes even inexpensive jewelry for their mother.

What is even more rewarding than the awards on their bookshelves they received in college are two certificates "awarded" to their parents as "China's Best Mother and Best Father" by ... themselves.
