Portrait at night, that kind of background is very clean, besides SLR, what brand and model of mobile phone can do it? Just like a photo.

Photos with clean background can be taken at the seaside, overpass or mountain top, and in places with relatively empty background. The background of this photo of hers is a little blurred, and the halo was added later, not the kind of large aperture background blur. It's just that the long background is blurred. It's just a better mobile phone, iPhone 6plus. Download a software with blurred background, such as camera plus, and add sunshine effect after shooting. There is similar software to add halo in Meitu and Light Shadow.
