A large number of engines using UCCI protocol can be obtained from the elephantbase website. (Beware, it is in Chines, and crashes my MS Internet Explorer, although I can view it fine with FireFox.)
The following is the list of engines I could download. 3DChess and Binghewusi currently seem the strongest. Coony and Jiaolong seem amongst the weakest (from those that play without trouble). Some I could not get running, they seem non-compliant with the UCCI standard, and hard-wired to play at one particular time control, which makes them forfeit without worry on any faster time control. Some do understand time contol, but are just a ittle bit too slow, and lose on time a lot (XQ Spirit, Elephant Eye). Perhaps the extra delay due to the adapter is the cause of this.

There is only a hand full of Qianhong plugins, but some of them are quite interesting if you like to have a chance at beating the computer. The Qianhong plugins can all be downloaded from here, and can be played under WinBoard through the QH2WB adapter. They currently use unpredictable time; perhaps in a future version of QH2WB I will let do the adapter the time accounting, and let it set the plugins for the highest level, and interrupt them (by sending a TIMEOUT command, which is the QH equivalent of the WinBoard 'move now' command) when the calculated time is up. This would still put them at a disadvantage to engines with proper time control, as interrupting a search in progress usually causes a lot of time to be wasted.
The main thing that is important to know about the Qianhong plugins is the levels they can run at. In principle you can figure this out by starting their executables from the command line, with a '-info' argument. They then print out everything that is to know about them. But just to save you some work:
Qianhong levels 1-3 VSCCP levels 2-9 Ki11egg levels 5-14 Elephant Eye levels 1-6
Note the latter is actually the UCCI engine running under UCC2QH, so running it as a QH plugin under WinBoard is needlessly complicated, using 2 adapters; it would be much better to run it directly through UCCI2WB.
To get a rough impression of the relative strength of the various engine, I conducted a round-robin of bullet games (40/1), where every engine played every other engine 10 times. This produced the following ranking:
