Jackie Chan : Chi of the Vampire (2002)
English
The Jiangshi, also known as Chi Vampire, is a Chinese Vampire capable of sucking "chi" (life energy) out of people and turning them into his vampire slaves.
In an abandoned castle where Uncle was acquiring rare antiques, Jade accidentally awakens the Jiangshi, which sucks out her, Tohru's and Uncle's chi. In a chi transfusion (similar to a blood transfusion, but different), Tohru gets a part of Jade's and Jade a part of Uncle's, making the recipient behave much like the donor. But when Uncle himself is affected, no one is available to effect the magic for the transfer, and so Uncle becomes a vampiric slave.
The only way to reclaim the chi is to find a toadstool in a graveyard, place it in the vampire's left sock, and throw it into a river before sunrise; otherwise, the chi will remain lost forever. The Jiangshi sets out to stop the Chans as soon as it learns of their intentions, but loses its socks and the chi it stole. As the sun rises, the Jiangshi is blasted into dust.
