and it looks a bit like yellow Chrysanthemum (Huang Ju Hua). The white one is a Chrysanthemum paludosum (Bai Jing Ju Hua). The third one is daffodils(Shui Xian Hua). And the last one look like Cercis chinensis Bunges or Redbuds (Zi Jing Hua), which are different from Bauhinia flowers or Hong Kong Purple Orchid (Yang Zi Jing Hua). Any different opinions?
