　　Last year, on August 22, 2019, my daughter was just born. On October 26 of the same year, I participated in the flight mission of Yaosan (Long March 5 Yaosan carrier rocket) and came to Hainan. After more than 70 days of mission, I Back to Tianjin. Just after January 31 of the next year, I came here to perform the 5B (Long March 5B carrier rocket) flight mission, 90 days. After returning to Tianjin for ten days, now I came here again to perform the mission of Yaosi (Long March 5 Yaosi carrier rocket). After almost returning home, the children hardly knew me.

　　In order to ensure the continuity and completeness of the work, many of us perform operational tasks continuously. Everyone knows that now our age group is performing tasks continuously in this shooting range. How much has been given, how many memories, and how many Time, indeed, we have always been very grateful to the family, and also to express our sincere gratitude for the support and understanding of these aerospace families for this opportunity.

　　[Explanation] Gao Fenghe from the Fifth Academy of the Aerospace Science and Technology Group is responsible for the test and command of the Mars exploration mission. He said that since taking over the commanding job, overtime has become the norm, so in order to facilitate his work, he lived in the unit dormitory for a period of time. It wasn't until later that his mother had a conversation with him that Gao Yuanhe chose to move back home.

　　"Think about you going home for one day or even half a day every weekend. This year you can only come back for 52 days. Your mother will live for another 20 years, which is about 1,000 days, 3 years. Think about your future In the 20 years of your life, you have not been married yet, and the time you can accompany me now is three years." At that moment, I deeply felt that my family was really too little, and then I retired the dormitory. After I retired, I would definitely go home no matter what time I got off work every day. I had a meal with my parents in the morning. Then go to work.
