"Two men talking in a room" is what you'll get in 60% of this show. 25% of the show has more than two but no more than ten men, or a man and a woman, talking in a room. And another 10% is two or more men talking outdoors... yup, you get the idea. Superficially, that's most of what you'll see in The Wind Blows From Longxi. And it’s also part of the show's very niche appeal.

Longxi checks all my personal boxes for a favourite drama— great acting, real historical events, tight plot, treacherous politics, and zero distracting romance. It’s one of my favourite shows of all time, if not my favourite show ever. In a nutshell, Longxi is about spies during the Three Kingdoms period. Chen Gong is a veteran Shu field agent embedded in Wei. A critical military campaign against Wei goes horribly awry due to wrong intel provided by Chen Gong. How did that happen? Where do Chen Gong's loyalties truly lie? These are the questions that Chen Gong’s sworn brother and in-law, Xun Xu (also an intel veteran), is brought in to investigate. If you’ve read The Tao of Spycraft or any of Ralph Sawyer’s other books on ancient Chinese warfare, many of the spy methods and tactics in this show will be familiar. Since defection and double agents are normal in spycraft, one question is whether the defection is genuine or just a ruse to gain the enemy’s trust. That’s the central issue in this show, which the poster caption 谋中谋 计中计 (“the scheme within the scheme; the plan within the plan”) encapsulates.

Plot: A very twisty plot that doesn’t strain credibility. The least headache-inducing way to follow the plot of this show is to ask whose interests are currently aligned with whose. Without saying too much about what happens (because that would really ruin everything), the whole plot turns on the constantly shifting allegiances of various players, at the highest and lowest levels of society, in the conflict between Shu and Wei. The plot is complicated but doesn’t tie your brain in a knot until the episodes hit the late teens. Thankfully, ep. 21 onwards provide the clarification you need. If you get lost, there is a 5 minute “Cliff’s Notes” recap at the end of every episode that summarises the key developments. However, you’re very much on your own when it comes to the finer plot points, which the recap doesn’t cover. The final resolution is elegant and gut-wrenching, and I am glad the team did not go for a happier ending. That would have been far less satisfying.

Script: The script doesn't waste any time getting the show off the ground, even if it seems that little goes on in the first episode (it's important background context and sets the scene for everything else). Overall, it's just the right length at 24 episodes. Since this is a hardcore spy-plus-politics drama, most of the real action takes place behind closed doors, with bearded, middle-aged men plotting and scheming over cups of tea. The dialogue is exquisitely political and worth following closely. We are treated to scene after scene of various players abandoning old allegiances and cementing new ones, and having those allegiances tested by their new masters. One such scene is the one where Feng Ying (Shu spymaster) seeks out Li Yan (Shu general), formerly from an internal “enemy” faction, to declare his allegiance to Li Yan. Feng Ying tries to get on Li Yan’s good side to protect himself from Li Miao (Shu interim mid-level "civil servant"), who also works for Li Yan, but wants to turn Feng Ying into a scapegoat for his own political purposes. Li Yan appears to believe this is a ruse by Feng Ying and tests him, but goes along with it as it benefits him in the short term. I also liked how there were relatively few flashbacks. The ones in Longxi are short and moving without being too sentimental; I especially loved the one where a ball lying by the door causes a very miserable Guo Gang to reminisce about playing cuju (蹴鞠?) with Chen Gong in the rain. Another striking thing is the judicious use of action scenes. Since Longxi is about politics and intel, there are only a handful of brief action scenes (mostly military skirmishes). Then in ep 23, the viewer is treated to the show's only extended sword-fighting sequence with Chen Gong. The burst of pure violence and pent-up rage in this sequence arguably makes this scene the emotional climax of Longxi. Chen Gong, like any good field agent, has iron self-control. At worst, he has quiet breakdowns in private, then quickly gets his act together again. But in the swordfight scene, he lets it all out. It's moment of pure catharsis for the character that sets the stage for the final episode. Definitely one of the finest moments in an already amazing show.

Themes: The 2 main themes of Longxi are (1) the moral neutrality of politics, and (2) that human relationships are a double-edged sword. The life-and-death political struggle between Zhuge Liang and Li Yan is not a matter of good versus evil (even if Li Yan does some truly terrible things), but down to a difference in opinion as to how Shu should ensure its medium-term survival. And at the end, it’s Chen Gong’s feelings for Di Yue (his wife) and Xun Xu that threaten his allies’ best-laid plans, even as his allies exhort him to continue making enormous personal sacrifices for Shu. For both Xun Xu and Chen Gong, what ultimately gives them moral closure and defines their biggest decisions is not self-interest or patriotism, but staying true to their loved ones. Powerful stuff.

Acting: Everyone put in an A+ performance here, except Angelababy. I have nothing against that lady, but she was pretty wooden in this show and looked so airbrushed. She also didn't quite click with Bai Yu on screen. (I don’t watch enough shows to comment on whether this is better or worse than AB’s usual...) Chen Kun was of course brilliant as Chen Gong, but I was equally (if not more) impressed by Bai Yu’s low-key but completely spot-on performance as the dangerously sentimental Xun Xu. Xun Xu has the smarts and EQ to be a great intel guy, but he's too emotional and high-minded for his line of work. He's terrible at lying and makes a few wrong calls that have serious consequences. One gets the sense that he has only survived this long due his kicked puppy expression that tugs at everyone's heartstrings, a good brain, and sheer luck. Bai Yu perfectly captured this precarious balance of vulnerability, world-weariness and cunning at the core of Xun Xu. His final exchange with Chen Gong, especially the delivery of「我看透了你的心」(“I’ve seen through your heart”) in ep. 24 was also a total tear-jerker. With a lesser script and actor, Xun Xu would have been a character whose naivete makes the viewer question how his head has managed to remain on his shoulders. But through the combination of great script characterisation and Bai Yu's acting, Xun Xu becomes a convincing example of the idealistic survivor who manages to keep going even after all the dust has settled. I also really enjoyed Edward Zhang’s performance as the Wuxian cult leader Huang Yu. He fully conveyed his character’s megalomania and cruelty with what little screen-time he was given. The actors playing Feng Ying, Guo Gang and Mi Chong were also absolutely brilliant. I loved them all!

Music: This was okay. It was composed by Kawai Kenji, but I was hoping for thematic music that was less Western in flavour. It was also disappointingly run-of-the-mill "epic"-sounding stuff. But it's not a deal-breaker for me.

All in all, 10/10, A++++ from this very satisfied viewer! For me, I’m not sure if any other mainstream period drama can compare with this show.
