The uncooked yolks can be used as ingredients in mooncakes or stuffed in zongzi (rice dumpling) of Dragon Boat Festival fame. A common recipe I've seen circulated among Chinese Buddhists also calls for a mixture of mashed yolks and grated parmesan cheese to produce a vegetarian "fish roe." But at the most basic level, the eggs are usually hard boiled and eaten with plain congee to offset the saltiness. Add some pickled vegetables, and this would be considered a light meal. This sort of meal, however, is considered quite "homey" and plain and, in my experience, would never be served in a normal restaurant or offered to dinner guests in a Chinese home.
