Chinese Tea Eggs

Hi guys, so I made an attempt to cook some "chinese tea eggs" a few days ago and I'd like to blab out the results of it. As you all know, I'm a completely clueless noob at cooking, so these eggs didn't come out up to my expectations. The color wasn't dark enough and the taste needs more flavor. But since it's only my first time making this, I'd give myself a B.

Here's the list of ingredients I used:

1. 6 large eggs
2. 4 tbsp regular soy sauce ( I learned that you should use the dark soysauce for better coloring and flavor)
3. 3 tsp salt
4. 1 small stick of cinnamon
5. 4 star annise
6. 1 tbsp tea leaves (I used green tea leaves, but black tea leaves are recommended)
7. 1-2 tsp sugar (I kinda forgot how much i used!)

Basically, I brought the eggs to barely a boil and then simmered it for 2 minutes. Take out the eggs and made lots of cracks on each so the sauce can sip in. Then used the boiled water and mix it with all the ingredients and put the eggs back in and then bring it to a boil again. Then simmer for about 3 hours (more for more coloring and flavor). Yup, so that's pretty much it.

P.S. the most difficult part of this was listening to my grandma yelling at me saying, "3 hours?! You're gonna make the eggs old!" But good thing I didn't listen to her, or else my eggs will just taste like regular eggs. -_-
