There is a bug (of sorts!) with Deepin 15.2 with Default applications.
As an example, take *.mp4 file. Deepin Movie will normally be set as the 'Default' application for these (as seen via Control Center->Default aplications). Now, right-click on a *mp4 file and select ''Open with other application'', and (for example) select 'Mediainfo'. Sure enough, Mediainfo now open the file - the problem is, that it willl continue to do so for all subsequent *.mp4 files for then on! This is despite 'Deepin Movie' still being shown as the 'Default' application for this media-type from Control Center->Default applications.
There should be a 'Remember selection' option, when an application is right-clicked on in order to open it with another application - as there is in every other desktop! Or it should at least defer to the 'Default' application as is already set. As it stands, after opening the *.mp4 file with Mediainfo, the user must then immedately right-click it again and select Deepin Movie with 'Open with other application' in order to restore settings.

This is silly.
