In 2013, Yao Yuan Hao postponed his birthday on April 19, as both the shooting schedule and his upcoming marathon were scheduled during that week. For the first part of the week, Yao was asked to swim in a lake on a cold day, describing the activity as: "...really cold, colder than washing with cold water in winter" He also mentioned that he made use of his time running during film shootings as practice for his participation on a 21-kilometer marathon scheduled the day after his birthday.
