The night before, rinse and rehydrate the lotus leaves in water overnight.

Rinse the dried shiitake mushrooms, and rehydrate in water for 2 hours.
Rinse the dried shrimp, and rehydrate in water for 2 hours.
Drain all ingredients before using them.
In a small bowl, add soy sauce, oyster sauce, dark soy sauce, sesame oil, five-spice powder, white pepper, and salt. Whisk together.
In a bowl, add 1 ¼ cup of water. Pour in ½ of the sauce. Mix.
Transfer the pre-soaked and drained rice to the pot of an electric rice cooker and add the water mixture. Mix. Use the setting for rice and cook.
In a large bowl, add the chicken thighs, soy sauce, Shaoxing wine, five-spice powder, white pepper, and salt. Mix well. Let marinate for 30 minutes.
In a well-seasoned wok, over high heat, heat it up until smoking. Turn to low heat, add 1 tablespoon of extra light olive oil. Immediately add the Chinese sausage, dried shrimp, and shiitake mushrooms, and stir until the aroma comes out about 1 minute. Remove from wok and set aside.
In the same wok, over high heat, heat it up until smoking. Add another tablespoon of extra light olive oil. Add the marinated chicken. Cook for about 3 minutes. Add the garlic and cook until aromatic, 30 seconds. Add the cooked sausage-shrimp-mushroom mixture. Then add the rest of the sauce. Stir fry until all ingredients are cooked through and combined, about 1 minute. Remove from wok and set aside.
When the rice is done, wait for about 5 minutes until it’s slightly cooled.
Place a lotus leaf quarter on a flat surface and pat it dry. Place another lotus leaf directly on top of the first and pat dry. Place 3 tablespoons of sticky rice in the center and form it into a rectangle. Then place 1 tablespoon of fillings, and 1 quartered piece of cooked salted egg yolk, over the rice. Add another 3 tablespoons of rice on top of the fillings.
Fold the bottom of the lotus leaves up and over the rice. Then, fold in the right and left sides, and roll the bundle upward until it becomes a rectangular packet.
Repeat with the rest of the lotus leaves, rice, and fillings.
In a steamer, bring water to a boil. Put each packet in the steamer, one by one, leaving a little space in between. Cover and steam over high heat for 1 hour.
