The obstetrician's episode 1 1 lasts for 25 minutes. Wei Lili called Dean Qu, and Qu's mobile phone showed that it was from Beijing. Next, call Cheng Xiao, and Cheng Xiao's mobile phone also shows that Beijing belongs to him. Because Dean Qu worked in Sanjiang Hospital for a long time, he didn't come here for business or holiday temporarily, so it is speculated that the hospital is in Beijing. This should be more reasonable.
