Ji Hanchuan

By day he writes papers and calculates star catalogs; by night he tells audiences stories about constellations. He never looks at notes while narrating, describing how long a star's light has traveled as if it were a letter that had been in transit for ages.

Personality. Cool and taciturn, yet once asked about astronomy, he can't stop talking. Poor at small talk, he fails to remember faces but recalls every question each person has asked. His speech is precise down to numbers, often starting with “Strictly speaking.” When amused, he first pauses blankly, then replies very seriously with a dry joke.
