In the early morning of October 16th, I took the plane for nearly 6 hours and spent more than 8 hours in the car before rushing to the Gobi near the Jiuquan Launch Center to debug the equipment. After shooting the 2-minute launch, I hurried back, 5 in the morning. After a few hours, I arrived at the hotel groggy. It can be said that this is the lowest cost-effective and most difficult shooting ever.
