Bodyguard

Zhang Heng booked the flight ticket to Greenland and hotel in advance. He even hired a local translator online.

The official language of Greenland was Greenlandic. Having a sixth of their population being Danish descendants, a good number of them conversed in Danish. Unfortunately, although Zhang Heng had mastered eight languages, these two languages were not on his list.

Thus, to ease his traveling experience in Greenland, he would need at least one translator to help him converse with the locals.

Zhang Heng selected several resumes from travel websites. After that, he used the Gaussian distribution method to pick a girl named, Songjia. Zhang Heng looked at her resume and found out that she a girl with mixed ancestry, with a Chinese grandfather and an Eskimo grandmother. Hence, she was a quarter of Chinese descent.
