Featured Help needed with origins of these lacquer plates

These two huge decorative lacquer plates measure over 45cm diameter each.

They are decorated with designs after the work of contemporary Chinese artists Xiaoyan Chen and Ting Shao Kuang

They seem to be a mixture of printing and hand finishing. Any thoughts on their origin?

They came from the collection of a family who were in China in the 80s and 90s

Thanks in advance

 

They look very much like a picture I have that was Vietnamese.

 

Google Images identifies the first image as inspired by the work of the Vietnamese artist Chen Xiaoyan. The second by the work of Chinese-American artist Ting Shao Kuang.
