'Dream Sea Visual Collection' aimed to restore the autumn scenes in the play, so the staff meticulously picked up all the dead branches. Spring Sheng @X玖少年团肖战DAYTOY and Sister Yan Qiu @张龄心 also wore thin autumn clothes while working in the weather below minus four or five degrees. To prevent 'smoke and mist' while speaking, on the suggestion of Hezi @尤宪超, everyone even held ice water in their mouths. Each person really put in a lot of effort! #TheYouthMemoriesBehindTheScenes# #TheYouthMemories#
