The Latin phrase, jus soli ("right of the soil"), is an unconditional right of a person born within the territory of a country to be conferred citizenship. Singapore's nationality law is based on jus sanguinis ("right of blood", in which citizenship is determined by that of one or both parents) and a modified form of jus soli (with at least one Singaporean parent).

These poems address topics like belongingness and birthright by exploring the intermingling of the four fundamental elements of air, water, fire and earth.
