It's important to understand that this word carries a lot of historical baggage and is considered offensive and racist in many contexts.
It's best to avoid using this word altogether and instead use respectful and accurate terms like "asiático" (Asian) or "persona de origen asiático" (person of Asian origin).
If you're looking for a specific description of someone's physical features, it's better to use neutral terms like "ojos rasgados" (slanted eyes) or "piel oscura" (dark skin) when appropriate, but be mindful of the context and potential for misunderstanding.
