This is a story related trophy.

Ghosts and Stuff
Complete all secondary content
The secondary content is the 10 side missions included in the DLC. They will all appear on your in game map. However, some will not be avaliable until you have completed a particular mission.
There are three types:
1. Captured Civilian (blue bubble icon);
2. Yaoguai (purple swirl icon); and
3. Jiang Shi (blue swirl icon).
1. Captured Civilian (3 side missions)
In these side missions you simply need to defeat 4 Jiang Shi to release the civilian.
1.1: Jiang Shi Basketball (available after completing "Trick or Treat")
1.2: Jiang Shi Park (available after completing "Chinese Magic")
1.3: Jiang Shi Garage (available after completing "Revenge x2")
2. Yaoguai (3 side missions)
In these side missions you need to defeat 4 Jiang Shi and 1 Yaoguai. To inflict damage on a Yaoguai you either need to have a full magic (face) meter or use a peachwood sword. Peachwood swords can be collected around the city at Yaoguai spawn points or by passing a Jiang Shi side mission. You can find the Yaoguai spawn points by looking out for single red enemy icons on your map. Some notable locations are in front of your apartment and in front of the main entrance to the Night Markets.
2.1: Yaoguai Alley (available after completing "Chinese Magic")
2.2: Yaoguai Parking (available after completing "Smiley Cat's Army")
2.3: Yaoguai Pier (available after completing "Smiley Cat's Army")
3. Jiang Shi (4 side missions)
In these side missions there will be infantly spawning Jiang Shi (but only 4 at a time). You need to throw 3 into the portal to close it. You throw a Jiang Shi in by grabbing it by pressing circle, dragging it to the portal and pressing circle again. Once closed, defeat the remaining enemies to finish the side mission.
3.1: Jiang Shi Court (available after completing "Smiley Cat's Army")
3.2: Jiang Shi Street (available after completing "Smiley Cat's Army")
3.3: Jiang Shi Overpass (available after completing "Clean Out the Rats")
3.4: Jiang Shi Street (available after completing "Ghost of the Past")
Once you have completed all 10 side missions the trophy will pop.
Achieve 5 Gold Awards
For this trophy you will need to complete the 5 brand new stat awards which are included with the DLC to gold level.
1. Vampire Hunter
Requirement: Kill 200 Jiang Shi
You will defeat around 100 Jiang Shi by playing through the story and completing the side missions. If you pass the main story, you will be able to find Jiang Shi around the city to reach the 200 kill requirement. They usually can be found around the money shrine locations. However, this can take some time as there will only be around 2 to 4 in any location and you will need to leave the area for them to respawn.
A better method is to save the final Jiang Shi side mission until after you have passed the main story. As the Jiang Shi spawn infinitely during those side missions until you close the portal you can obtain all necessary kills in one place. Simply lure the Jiang Shi away from the portal so you don't accidently throw them in and get fighting. It should take you about 10 to 15 minutes to kill 100 Jiang Shi using this method.
2. Demon Hunter
Requirement: Kill 20 Yaoguai
You will kill around 10 to 15 Yaoguai by playing through the story and completing the side missions. To obtain the remaining kills drive around the map looking for single red dots indicating an enemy. If at the enemy location there is a peachwood sword, pick it up and a Yaoguai will spawn. These locations can be used infinitely, so simply leave the area and return or head to another such location to rack up the rest of the required kills.
3. Demoic Exorcism
Requirement: Kill 15 Yaoguai with a peachwood sword
Peachwood swords can be obtained from the Yaoguai spawn points (such as in front of your apartment and in front of the Night Markets), during the story or by passing a Jiang Chi side mission.
I recommend that you use the method described for Demon Hunter and always bring a sword to the Yaoguai side missions and you should have this one in no time.
4. Hart to Get
Requirement: Avoid 100 Jiang Shi Bites
Avoiding bites is the same as countering an attack during the main campaign. Simply press triangle when the Jiang Shi glows red and you will counter/avoid the bite. You should obtain this while playing through the story and side missions. However, if you find yourself short, complete this at the same time as grinding out the remaining kills for Vampire Hunter.
5. Underworld Offerings
Requirement: Find 10 Hell Money Shrines
See Hell Money.
Find all the money shrines
To collect this trophy you just need to drive around and use each of the Hell Money shrines. There are 10 in total. Often there will be Jiang Shi around them, so you may need to defeat them first. I have prepared the map below to assist. The shrines are marked by a yellow dot (note: the items from the main campaign will not be there in the DLC, they are just included for the sake of detail).
