A middle-aged man residing in Official Shelter No. 9. He is a husband and father who volunteers for dangerous surface work during the radiation storm to earn triple pay, hoping to improve his family's difficult circumstances. He wears radiation-proof suits issued by the shelter and travels to work sites with rest stations every few hundred meters. Zhao Haihua is concerned about his family's health issues—his wife is anemic and needs supplements, and his child Yuan Yuan suffers from headaches and insomnia. He is also worried about potential reductions in daily food rations. Despite inner unease, he reassures his worried wife and promises to return safely after a three-day work assignment.
