I also found a walkthrough: https://tieba.baidu.com/p/5023967656
And a video (you need to wait for the ad to finish): https://www.99hui.net/v/XMjk4NDIyNzAwOA==.html
It says that the BT map is hardcore. It looks interesting.

Thank you, I couldn't find it on Chinese sources. Yes, I found its description, that there are 2 versions: easy and hardcore. I want to play it without any tips or hints. There is a video walkthrough on YOKU in Chinese:

but I intentionally don't watch it! I plan to play it on the weekend.

Looking at the map in the editor, it seems very easy at first glance: capture nearby castles, gather resources, and free your heroes from prisons on the map (there are no taverns in the castles at the beginning). It's best to do everything quickly. But in the prospector, you can see that the enemy bosses and sub-bosses with legions of creatures need to buy a certain number of snipers, and then they will "wave-like" come to our respawn points, I don't know how to kill them. The magic is also "standard": city portal and clone are available in one copy for the mages (you need to get there), blindness and forgetfulness are only available for our 2 heroes in the prison, there is no flying magic, you can collect sets of artifacts, at the start, the AI gets +100k gold and resources, then every 2-3 weeks, the castles get 2-3 weeks of additional growth + construction, in 3-5 months, taverns appear in some cities (I assume, for the AI).
Overall: the map is designed for speedrunning: we kill the AI that hasn't developed yet (even though they have larger armies at the start), literally in the first 2-3-4 weeks, we free as many of our heroes as possible, especially Jela for the snipers, and most importantly: get to the key magic of the city portal. Ideally: we gather an army (including 1-2 events on the map), and we kill the AI before it starts to spawn, although I think this is unlikely. Probably, I will have to capture all the castles to the maximum, and then, with purely partisan raids, buy up the growth in the castles, and immediately sell it, i.e., deprive the AI of reinforcements and escape with the city portal. We beat whoever we can. As an option, we allow the enemy heroes of the same color to consolidate their armies on one of them, and we eliminate the rest of the "easy targets" without armies (there is both a plus and a minus to this strategy). Like a couple of previous Chinese maps that I played, I feel that this one will be a real challenge. :)
