Add the spiced rum to a chilled Collins glass over ice.
Top with ginger beer.

*Chinese-five-spiced rum: Using a funnel, add 1 tsp Chinese five-spice powder to a 750mL bottle of Gosling's Black Seal rum, and shake vigorously. Let set for at least 1 hour but preferably overnight. Strain the rum through a coffee filter set inside of a large strainer into a bowl, then funnel back into the original bowl and label.
