This is one of the popular dish which can be found in China Hainan, Wanning (basically my hometown) call Hou An Fen Tang (後安粉湯) cooked by my mother.

First ,clean the pork intestine and pork stomach(suggest to stuffed some ground peppers inside first), then marinate the lean meat with sesame oil and soya sauce, after that boil big pork bone soup, with the pork intestine,pork stomach ,pork liver, pork ribs and marinated lean meat, add salt and pepper moderately and then boil for 4 hours ,while waiting to boil, fry some chopped garlics chopped some veggies and spring onions.

When the soup is done ,basically just take out everything except for the pork bone and chop into smaller pieces. Then bring out the soup and boil ,put in the kway teow and chopped meats etc. Add an egg, vegetables ,spring onion and fried garlic when the kway teow is ready.

Suggest to go Hainan Wanning to try the authentic one. Will not regret !
