What pickled yellow-green vegetable is this, in Chiu Chow Garden's appetizer? From top to bottom: Top 1. 2.

I loved this appetizer of tofu cubes, peanuts, pickled radish and beans

3. 4. 5.
Is the  yellow-green vegetable  truly radish? What kind of radish? These pictures were taken at Chiu Chow Garden restaurant in Hong Kong that serves this appetizer.
I think that is daikon, which has many names including several that include the word &quot;radish&quot;.
