You first meet Quickhand Zhang in Phantom Blade Zero 's Crimson Forest and, assuming you free him, arriving at the Thieves Camp and his first hideout, he quickly recruits you to find his counterparts and unmarked treasure in each region.

I've included videos below of where to find Zhang's hideout and the jade treasure chest locations in each region, plus corresponding text entries that explain what you'll need to do to reach each in terms of battling enemies or grabbing any keys required.

Reward : Flying Dagger (Phantom Edge) - Thrown knives that apply poison buildup.

From the Outlaw Trap bell, head into the cave directly behind you with the butcher and the dogs to grab the Crimson Forest Tunnel Crank. Use it to unlock the grate in the floor near the bell, drop down, descend the ladder, cross the wooden bridge and defeat the second butcher and dogs, then take the left path up a slope to where you'll find the chest.

This second chest is behind the locked Thieves Camp Dungeon gate. To get the key, progress through the Crimson Forest until you arrive at the Cliffside Lodge. Head upstairs to grab the cellar crank, unlock the cellar, then drop down to where you can spot the corpse with the glowing item (the key) below you. Unlock the gate back in the Thieves Camp to find the chest immediately on your right.

The third chest is in a cave near the Thieves Camp bell. Exit the camp via the path heading towards Zhang's Hideout, follow the path down around the cliffside into the cave, then fight past the dogs and their master to find the jade chest on your left.
