I mean... yes, sort of? I actually have a couple of those, I just put together a bonsai tree set from "JIANPINWORLD" a few days ago. It's a nice set design, but the quality is... not good. The fit of the pieces reminds me of Megablocks sets from the 90s, which is to say that the brick tightness is very hit-or-miss. The set involved putting little flower pieces onto sticks, but the holes in the flower pieces varied considerably, sometimes too tight to fit on the stick and sometimes too loose to stay attached. There were small hook parts, two of which cracked in half while tying to connect them, and there were no spare parts included. The coloration of the pieces is inconsistent. The instructions are also poorly laid out and badly printed.

The sets you're talking about are very much an example of "you get what you pay for".
