I think I also have Hung Sheng Spice. It is unfortunately very very very slow grower, which is very strange for this type of paphs.
I bought it in bloom (mine happens to be quite colorful and the leaves are narrow & long) in Jan 2017. The old growth is long gone and the newest growth is still growing. Over three full freaking years!!! It was literally like one leaf a year. I was so close to just tossing but the flower was memorable and the plant was finally looking a bit better this year with better roots and all, so I'm keeping it. It may even bloom again some time next year. Or so I hope. Fingers crossed!!
I had a terribly shaded picture on my phone for some time, but I must have deleted.
The flower looked pretty much like a straight spicerianum but slightly larger and with pronounced dark purple on the dorsal.
