I was curious, so I googled the Chinese name. Maybe you already knew the description, but for anyone who might be interested, here is a modified Google translation:

The variety is early-maturing, high-yielding, height 200 cm or more, pod uniform, dense, flower node starts low, round stick-shaped pods, 20-25 cm long, tender, white, fleshy pods, less stringy, good quality, about 60 days after sowing, began picking tender angle, about 2500-4000 kg per mu. (1 mu is 666 square meters)

Sounds interesting. Did you get the seed packet in the U.S.?

I think that is offered at Asian supermarket. Some of my friends grow it, but I do not. I do not know what kind of bean it is.

Looks like two differnt varieties of common bean (P. vulgaris) round pod type definitely not a flat pod Romano type. The second photo reminds me of an old white podded pole wax bean offered by Burpee around 1900. White Zulu.

They are the same variety, with one slightly improved. The color difference may come from photo taking.

The name on the first photo reads "New Improved Nine Seeds White", and the other "Superior Nine Seeds White".

They are the same variety, with one slightly improved over another. It is like Blue Lake 100 or Blue Lake 110...

Apparently it is a white wax bean based on the names and description provided by pennypond

The names do not really say anything.

It is one of the common beans, the Phaseolus vulgaris. They are improved local variety and very popular in China.
