You’ll find that they each have coordinates listed for trainers that will give you new skills

With these notices, you're able to acquire new attack skills to use Runescape Gold in combat. Each time you get a new notice, open your inventory (ALT-I) and select the "Quest" tab.

Under that tab, you'll see the notices you've accrued, and upon inspection of the notices, you'll find that they each have coordinates listed for trainers that will give you new skills.

After you choose your new skill, return to Master Zhao (160,157) to receive your next quest entitled, "New Friends." He will send you to Dragon Chien (145,139), who will give you a 5 question quiz that you must answer correctly. Once you complete this, you can return to Master Zhao (160,157) for another recommendation notice!

After you choose your next skill from the notice, return to Master Zhao (160,157) to receive the quest, "Try to Be a Warrior." Travel to Mr. Sun (173,146) and he will give you fireworks to detonate in town. Go to the target location, open up your inventory (ALT-I), and activate the "Signal Fireworks" to complete the quest.

Upon returning to Mr. Sun (173,146) from quest completion, you will be sent to Master Zhao (160,157) to receive your third recommendation notice for a new skill!

After you choose your third skill, return to Master Zhao (160,157) to receive your first combat-oriented quest called, "First Kill." You are given the task of killing 8 Flatlands White Apes in the Wild Plains, to the west of Da Li.
