Hi Bruce - I was not even aware of Panoramio until I found this picture. I found these photos from doing a plain old image search on Google for "chinese pig oven" and, to my surprise, I saw something very familiar! To answer your question, yes - I am of Chinese descent and I too am See Yip. I have only briefly browsed through "Sons of the Soil" when it was published and I'm not sure if our family is mentioned.
I moved to Auckland more than 30 years ago and have just celebrated 30 years of marriage to my wife Alda earlier this year! But, I do remember working the fields with my brothers and my parents - and then harvesting the "fruits" of our labours ... through all weathers. I even remember some bright sunny days during the winters, it was so cold we had to wait until later in the day to pick brussel sprouts because they'd frozen over during the night!! So we had to wait until they thawed.
