In works such as "Honghu Red Guard", "Shangganling", and "Southbound", there are also characters called "Baiyulan", but the actors who play these characters are not the same as the aforementioned actors, and these characters are not directly related to Baiyulan in the plot and character design of "Red Arrow", "Deep Residence", and "Glorious Era".

Meanwhile, as the cast and character settings may vary due to factors such as version and production, the above information is for reference only, and the actual broadcast of the series shall prevail.
