C.L.I.F. 4 is slated for a broadcast in the second half of 2016
Although nothing’s really confirmed at this point in time, we heard through the grapevine that everyone’s favourite police drama series is making a return in end 2016. No one knows what the story plot revolves around or if a similar set of actors will be used for it, so we’ll take the chance to prophesise and share what we hope to see in this returning sequel. Story planners and writers, you may want to start taking notes.
What we hope to see: The drama has enjoyed a good run the past three seasons but we think it’s high time to call for a change – not in actors, but in its setting and storyline. Think along the lines of what was done with TVB serials like Heart of Greed (HoG) and Moonlight Resonancewhereby the original actors of HoG returned to do a “spiritual sequel” with an entirely different story premise altogether. The recurring casting hit a sweet spot naturally, but its same-same-but-different approach in its story plot that made it an even bigger hit with viewers.
The same can be done for C.L.I.F. 4 too. Focus it on a different uniform group instead and have it set in the air force, a police training academy or an army boot camp instead – what we’re saying is there are endless possibilities here. This also gives the producer enough reason to resurrect fan favourite characters who at one point or another died in the three-part series. How’s that?

不是猜想是设想，应该是给编剧看的。
个人只希望第四部南星的戏份能多一些，不要再当绿叶了，其实开一个全新的故事也不错啦，蓝天他们爱都恋了，婚都结了，第四部除了生娃也没啥可写的了，总不至于让他们离婚再复合吧

这种设想完全可以，否则就没新意。

我比较关心，瑞恩能瘦回来么
