Yes.

Just pay attention to the following.

Preserved eggs cannot be eaten together with eel. Although preserved eggs contain a large amount of protein, preserved eggs are alkaline foods. Although eels are also delicious, eating them together with preserved eggs can cause diarrhea and food poisoning. [4]

Preserved eggs cannot be eaten with brown sugar. Since preserved eggs are an alkaline food, while brown sugar is acidic, when preserved eggs and brown sugar are eaten together, the acid will merge with the alkaline, causing an acid-base imbalance. Therefore, the combination of brown sugar and preserved eggs can cause stomach diseases and mild food poisoning. Similarly, preserved eggs cannot be eaten with white sugar or rock sugar.

Preserved eggs cannot be eaten with soft-shelled turtles. Because in the mutual conflict between foods, soft-shell turtle and preserved eggs are mutually incompatible foods, which can also cause food poisoning and vomiting.

Preserved eggs cannot be eaten with plums. Preserved eggs and plums together can cause food poisoning. [2]
