This needs a lot of reworking in detail:
In a manner of speaking, I would graduate from Shanghai University College and set foot in social works.
Firstly, 'in a mannerof speaaking' doesn't fit here. If yougraduate 'in a manner of speaking', I would interpret that as an unsuccessful graduation. Secondly, shouldn't it be 'will' not 'would'? I wouldn't use'set foot'; this means enter something and not stay long, rather than embarkon a career in social work (no's')
