"Orange Juice of China" in Puerto Rico? No—It's Just Jugo de Naranja

There is no Puerto Rican term "orange juice of China" (jugo de naranja de China). Orange juice in Puerto Rico is simply called jugo de naranja or jugo de china—where china is the local word for sweet orange (distinct from naranja, which can refer to bitter/Seville oranges). The phrase "orange juice of China" appears to be a literal mistranslation or confusion. Puerto Ricans say "jugo de china" for sweet orange juice, not "jugo de naranja de China." No historical or cultural basis exists for the longer phrase.
