Ginger Vinegar Soup - third times the charm

As we get near the baby's due date, I have to make this ginger vinegar soup, to eat after I give birth.  It supposedly helps with the recovery process and it's a Chinese tradition to eat it.  But it takes a while for the soup to be ready, like over month of cooking on-and-off, so I'm starting to cook it now.

I totally forgot how to make this vinegar soup and am thankful I blogged about it the last time.  Here's the post with the recipe:
