Dusan,
I don't think you have seen the Korean war bows I mentioned. They are very similar to a bigger more robust form of the target bow. They have the same form of
kasan to use the Turkish word and the tip is the same as a modern Korean target bow but thicker.
Look at MAC 1991-0873 in the Grayson Collection Database.

To quote the catalogue:
147.5 cm nock-to-nock around curve; 5.1 cm wide at mid-limb; 1.8 cm thick at mid-limb.
Also MAC 1998-0112, which is described
Length is 164 cm; mid-limb width is 5.2 cm; mid-limb thickness is 1.7 cm.
These bows are bigger and more robust than Korean target bows and conform to Korean subscriptions of war bows. There are other bows that resemble Qing Manchu bows. Due to the relationship between Qing China in the latter part of the dynasty, it is likely the Qing style bows are either gifts, purchases or built to conform with Qing military regulations.
I agree that we were discussing more theoretical historical questions in this thread, but it is best to start one's theory from accurate facts. The problem I saw in the thread was that no one had commented on the difference between the structures of the two types of bows. It seemed to be based on profiles which do look similar. Looking at historical bows in the flesh reveals that the similarities are superficial. This does not invalidate the proposition that there are connections between the two types of bow. I think that the late Yuan and Ming bows were part of a continuum of bow types characterised by set back handles, short working limbs and long kasans. However, there is a native tradition of bow building in Korea that seems to have absorbed these ideas without giving up rectangular-sectioned kasans and a number of other features. On the other hand, Korean bow making tools and approaches are so similar to equipment from China to Turkey that one is forced to assume there was a common technology despite distance and the difference in bow design.
What I think has been missed is that, excluding the Turks, everyone in contact with steppe cultures after the 1600s moved to using bows with longer draws and heavier arrows. At the same time, muzzle loading guns like muskets became common as the long distance weapon of choice. It seems that the bow became the medium range weapon preferred by horsemen because their rate fire was higher than any combination of pistols carried on horseback. Guns had initially resulted in heavier armour being used to counter their penetration so bows had to deliver a more energetic and penetrating arrow to compete. Later armour was discarded because it was ineffective against guns making the arrows more effective. It is interesting that in the Austro-Hungarian Empire, armour was given up fighting on the Western fronts against European foes while it was retained on the Eastern front against the Turks and their Tatar auxiliary cavalry. However, archery never came back as major weapon because its advantage was on horseback and missile cavalry was in decline in general as infantry tactics improved.
