Which small train manufacturer is good in Xingyang?

In May, I visited the factory of Sanchuan Amusement. There are many types of trackless trains in their factory, including large trains for scenic spots and small trains for shopping malls and squares.

I visited several manufacturers in Henan, and none of them produced small trains with their own characteristics. It is suggested that the landlord go to Sanchuan for sightseeing.
