"Attention to each number, I am number zero, 30 minutes to prepare." The Shenzhou 13 spacecraft ignited the 30-minute countdown to launch. Wu Hua, the commander of the Shenzhou 13 mission zero and senior engineer of the Jiuquan Satellite Launch Center, served as the full launch area. "Commander", issued the "Shen XIII" launch preparation password.
Wearing aerospace overalls and a pair of rimless glasses on the high nose bridge, Wu Huaduan sat in the center of the test and launch hall, meticulously staring at the test screen, calmly reaching the command command.
This is the first time he has served as Commander Zero for a spacecraft launch mission. Behind his calm and calm command lies Wu Hua's 22 years of mission experience and sufficient mission preparation.
"There are his books everywhere on the bed, dining table, and sofa at home," said his wife, Chang Yanling.
Walking into Wu Hua’s office, there are more than 20 books on the bookshelf on the manned space flight series and CZ-2F carrier rocket, all of which have been specially marked by him. 10 thick reading notes record his six months of night reading. Experience.
"Although he was backing up No. 0 in the God 12 mission, he trained and prepared according to the standard of the main post. He studied and mastered the test and issuance procedures, plan plans, collaborative procedures and other test documents of each system more than three months in advance. Fifty or sixty books." Old partner Deng Xiaojun said admiringly.

Love reading is a habit that Wu Hua has cultivated since the beginning of his work.
In 1999, Wu Hua, who dreamed of becoming a scientific and technological worker, graduated from Harbin Engineering University.
In November of that year, as a new recruit, he participated in the launch of the Shenzhou-1 spacecraft. “The first time I saw the measuring and launching hall, I felt very technological and sacred. I heard the commander’s voice echoing in the dispatching broadcast. With an impassioned password, I yearn for one day I can become a test and distribution commander."
Once dreams sprout, unlimited creativity will breed.
Facing a telemetry position that is not compatible with his major, Wu Hua is not discouraged or afraid of difficulties, but settles down and spends all his spare time on self-learning.
He did not play poker or games. He spent the spring, summer, autumn and winter with Wu Hua with professional books and research projects.
"To engage in technology, we must rely on strength to speak and rely on technology to settle down and live." This is Wu Hua's work creed and his self-demand.
In a mission at the end of 2001, there was a problem with the compatibility of the GPS stand-alone. Wu Hua proposed an alternative method to troubleshoot the problem. It took less than two hours to smoothly eliminate the fault.
If the conventional troubleshooting mode program is adopted, it will take at least 3 days, and the task will have to be postponed until after the Spring Festival.
"Among the scientific and technical personnel, he is more innovative, bold, daring to question, and courageous to put forward his own ideas and solutions." Speaking of Wu Hua, Lu Jinrong, the former deputy chief of the center, gave a thumbs up.

For twenty years as a day, Wu Hua devoted himself to his career and continued the "996" work model, unable to accompany his wife or control his children.
"The day before we got married, he was busy with tasks. The day after we got married, he went to do tests again. Only on the day of the wedding, he took a day off." For the husband’s family, and the wife of an astronaut, Chang Yanling Very understanding.
Wu Hua, who has been busy with work for a long time and neglected to take care of his family, tried every means to run a small family as soon as he had time and energy: phased counseling for his children, summarized the easy points, accompanied the children in sports, took the children to watch the launch; took the initiative to help his wife Do housework, buy groceries, cook, and clean together...
"My son is 11 years old this year, and his mother has always been taking care of him. During the holidays, the birthdays of both parents, etc., it is the wife who fills the seat. Her support and tolerance have allowed me to have no worries and can work without distractions." Tan Picking up his wife, Wu Hua's eyes are gentle and apologetic.
"It's cold at night. You should pay special attention to the temperature, product status, and propellant concentration in the enclosed area of the tower, and report any problems at any time." In the early morning before the launch, Wu Hua boarded the 11-story tower and told Yang Jiawen, a tower attendant on duty. .

After the Shenzhou 13 ship-and-arrow combination was transferred to the launch area, Wu Hua started the "007" working mode. He had board and lodging at the position. During the day and at night, he would go to various locations at the launch site to provide assistance to more than a thousand sets of facilities and equipment. Carry out inspections and inspections to ensure that the enclosed area of the tower, including peripheral pipelines, cable connections, sand prevention and heat preservation, lighting and other facilities and equipment, does not have any hidden risks.
Wu Hua said that for manned spaceflight, there is no upper limit. Any minor omissions or poor considerations may have a great negative impact on the entire mission.
As a commander of No. 0, he must not only control the situation, but also take the left and right sides and grasp the details.
"Youth is for struggling", the youth of struggling is the most beautiful. Wu Hua deeply integrates his youth into the aerospace industry of the motherland, blends into the great desert, and blends into the long journey of a space power.
"Building an aerospace power requires several generations of people to work hard and continue to struggle. I am content and happy to be able to participate in this cause and do something meaningful." Wu Hua said with a smile.
