Carefully peel the shells off the century eggs. You can use a spoon or your fingers to crack the shell and remove it gently. The eggs will have a gelatinous texture and a greenish-gray appearance.

Cut the century eggs into small, bite-sized slices. You can slice them into quarters or chop them into cubes, depending on your preference.

Peel the cucumber and cut it into chunks or thin slices. Set aside.

In a small bowl, combine the soy sauce, rice vinegar, sesame oil, and sugar. Mix well until the sugar dissolves.

In another mixing bowl, add red chili pepper slices, chili powder, minced garlic, and roast sesame seeds. Heat a tablespoon of olive oil in a saucepan and then pour into this bowl.

Combine the sliced century eggs, cucumber chunks, cilantro, and green onion. Pour both dressing bowls over the ingredients and gently toss to coat everything evenly.

Enjoy your homemade Chinese century egg salad!
