Jade Statues are used to upgrade the Melee Skill. All of the statues are marked on the map upon completing Tiffany's Song mission, but you may see where all eleven statues are on the Interactive Map.
It should be noted that once you complete Tiffany's Song and Listening In mission, you can go around the whole island and retrieve all the Jade Statues -- except for three -- and really give Wei Shen a lethal boost in martial arts.
The first Jade Statue is in Club Bam Bam's VIP Lounge. You will need to complete Club Bam Bam to access this area.
Second, On a boat at North Point Waterfront; easily found while doing the cop mission Popstar Lead 3 when Wei needs to get on top of the boat's roof. The statue is on the marked boat.
Third, Inside the Golden Koi restaurant's kitchen. You can get it during the Listening In mission or just come back in during "free roam" mode after that mission.
Fourth, is in the Northpoint Temple. Check the highest abode's altar for this item.
Fifth, is in The bridal shop near Sammy Ho's place in north Central District (the circular plaza on the map). Easily visible when playing Bride to Be; you can spot it in the cut-scene with Peggy. You can get it after the Bride to Be cutscene if you are quick about it.
Sixth, Cemetary in Kennedy Town. Check the lobby of the funeral home.
Seventh, is in the K-Bar in Central.
Eighth, Inside the hospital in Central. Check the information desk.
Ninth, On the offshore gambling den north of Central's coast. You need to complete Riffraff Disposal first.
Tenth, inside Two Chin's mansion in Kennedy Town. You can only get this during Bad Luck since it is one of the mission objectives. If you miss the mission, replay i tfrom the Social Hub (on your pause menu).
Last one is in Vivienne's Penthouse in Central's Commercial District. You may enter it after Conflicted Loyalties is completed.
Hope this guide will help you, thanks
