Shanghainese Salted Pork Soup (yan Du Xian)

"This one's for the true Chinese cooks out there: Yan Du Xian (Shanghainese Salted Pork Soup with Bamboo Shoots and Tofu) is a rich and deliciously savory soup. That clear pork broth may not look like much, but believe us when we say, it's the nectar of the gods. "
