Thank you for your timely reminder.
That is really important.
"专业现在的“热门”、前景好不完全代表着未来就业方向的“热门”、前景好"
That is definitely right.
The title is attractive, however the title itself won't bring you anything.
Landing a wanted job is all it about, especially the one with strong cash flow.
That's why we focus on the current tendency, meanwhile do our homework on its track, doing our best to predict its future.
Good luck. :)
