Love is the Opiate

Love Is The Opiate is a side mission in Red Dead Redemption.

Story
A chinese immigrant named Zhou is an indentured servant for the butcher. He tells Marston that his love is waiting for him back home and he can't return to her because he's a slave to the butcher. The butcher tells Marston that Zhou is under contract, and if he breaks that contract he'll owe the butcher $10,000. He then says that if Marston brings him a white stallion he'll give Zhou his freedom.

Walkthrough
Starts in El Matadero. Go to the area on the map marked by a picture of several horses running, just to the north of Diez Coronas. Look for a herd of horses, lasso and tame one of the white Hungarian Half-Breds, then ride it back to the Butchers. Hungarian Half-Breds are white in color and are healthy; the sickly-looking horses are not the ones you need.

Note: If you have already tamed a Hungarian Half-Bred horse and have purchased the deed to the horse, you can simply call a Hungarian Half-Bred to you and deliver that horse to the Butcher. You may have to save and reload the game for it to register that you have a Hungarian Half-Bred to give to the butcher if you use the deed, just look for the purple "?". Alternatively, these white stallions can and have been found for breaking in Mexico, though seem to be as rare in appearance as in America.

Zhou will be set free and in a few days time Zhou can be found again at the train station in Chuparosa. He appears to be high on something (most likely opium, hence the title of the mission, Love is the Opiate). Speak with him to watch a small cutscene to complete the mission. Receive +50 Fame and +100 Honor.
