Master behind the scenes (ancient funny case solving)
Hok Gaing Hung Sum
On the first beat
Police sniper (police trilogy, you don't have to think about it to know that there is a case)
Shi Sheng Renjie (and some others)
Game-writing protocol book salt owl (these are not formal cases, but there are cases in the plot)
Mysterious family (this movie kills you from beginning to end)
Young master, the four famous arrests (solving the case is not bad, but a little ...).
Walking with the enemy (damn it, it's black, because of a problem caused by a case)
Royal idlers (alas, this pace is relatively easy, although it is also a case-solving)
Race against time (a word is cold)
Anti-porn pioneer
Trap a liar
I can't accept corruption
Witness protection team (a little old, but not bad)
Empathy (some parts are quite scary)
Breakthrough action (poor, progress)
The new king of law 1.2
Very big (of course, if lawyers also have cases)
Forensic pioneer 1.2 (needless to say, but I think they use too many precision instruments, which is a bit tasteless)
A strange detective (funny to solve a case, relying on spiritual strength)
O record 1.2 (classic among classics)
Zhiyong new policeman (200 1 film, but Hong Kong dramas are still good to watch at any time)
The first place is Huang Ting (there are five, so I haven't seen them much because I am older).
Panic and depression pursue each other (suspense)
Detective Wolong's love insurance (male silly, Wong Tze Wah, female Korean)
Private files of extramarital affairs (Guo Aiming and Guo Jinan, you can know from their names, this is a case caused by emotional affairs, similar to detective investigation files).
Detective investigation file 1.2.3.4 (I really don't need to say this)
Strange case of Shi Gong (the second part will be released soon, haha)
Wesley (this is the first play I know about Yoyo Mung)
Unfair record 1.2 (I prefer 2 relatively)
Scholars love soldiers.
A scholar meets a soldier (this is one, and there are two above, but I think one is more funny, although it is all about solving crimes)
Murder the city (the protagonist is not my favorite, but the plot is actually good)
Iron mouth and silver teeth (Ashe and Jordan chan's partner, funnier)
A spokesman for knowing the law (as I said, having a lawyer is actually similar to having a policeman)
Life circus (triggered by a treasure, good guys and bad guys fight wits)
Fantasy wave (this is a unit drama)
Tell a hundred lies (during the Republic of China, I fought wits for the heroines Xu Zishan, Bosco Wong and Sammul Chan).
Psychic detective files
A wise man
A plum blossom of a strange man (the heroine is too miserable, although the front is quite funny)
Anti-smuggling (another old movie)
Detective Dundee (Wong Tze Wah and Ada Choi's wonderful partner, I can only say that it is really good, that is, the male ending ...)
9000 felony (old film)
CIB criminal intelligence section
Oh, that's probably all I remember. If the moderator has any questions about Hong Kong drama, please leave a message and say hello. I am a big fan of TVB.
