A Chinese undead. Often called a "Chinese hopping vampire".
They drain people's life energy, hence the "vampire" denomination, although they are more similar in concept to Western zombies.
They usually have fulu or ofuda (strips of paper) stuck to their foreheads and their arms outstretched in a zombie pose. Modern iterations are often seen wearing a rimmed round hat known as a qingdai guanmao, referencing how Chinese officials under the Qing Empire were viewed as bloodthirsty creatures with little regard for humanity.
Use this tag when the person is an actual jiangshi. Use jiangshi costume when the person is simply dressed as a jiangshi, such as for Halloween. One indicator is the presence of undead features, such as colored skin or a mindless expression.
