Dr Doctor. My question is, do we wash the herbs first before we make the soup? Secondly, I noticed you mentioned all other countries suitable, are those all sits on the northern hemisphere, which seasons, coincide with Hong Kong, China and most South East Asian countries. A lot of Chinese live in the southern hemisphere, namely New Zealand, Australia etc where the seasons are in reversed. Do we reverse the METAL, WOOD, FIRE, WATER and Earth in our approach to applying these concepts to our Food and Drink which are aligned to the seasons. I have asked many masters in KZbin but so far no one took the time to respond to my question (s). Thank you. I like your soup and I will endeavour to make it as soon as I can get all the ingredients. Final question, can I substitute Fish bones instead of Pork bones? I do not eat animal meat or Poultry meat. Thank you. Looking forward to you advise and reply. Thank you again.
