The catalogue details of weights in the site that "alpha" has linked to appear to be much the same as in my copy of a Zibo Zhaohai trade catalogue I received in 2000. In fact, there are some (many?) identical images, with only the reference codes changed.
For example, "Modern Flower Design 022" is exactly the same as the ZH1022 and ZH1023 images in the Zibo catalogue. Click here to view
(top of front cover of catalogue included in the image for clarification of source). Also, "Modern Flower Design 016" in the linked site shows the same weight to left of the pair as in "022" - and that exact pair also appears on another page in the Zibo Zhaohai catalogue.
Perhaps "Zibo Zhaohai" has become "Ching Yan"??
In my image, you can also see that the lower two weights on that section of the page include, on the left, a flower design which is very much like the one Alan has referenced at the start of this thread. That design, with two leaves at the base of the stem and four leaves behind the flower head is seen in several examples in the Zibo catalogue. The treatment of the garland of canes and the details of the flower differ, but the design has clearly been a standard one for at least eight years.
