Here's why:
* "Camisa de chino" refers to a specific type of men's shirt with a distinctive collar. This style of shirt, with a collar that stands up stiffly and has a small, pointed band, became popular in the Philippines in the late 19th century.
* The term "chino" in this context does not refer to China or Chinese people. It is a Spanish word that can mean "Chinese", but it was also used in the Philippines to refer to a type of fabric, chino cloth, which was popular for shirts.
* The shirt's origin is not definitively known. Some theories suggest it may have originated from the "barong tagalog", a traditional Filipino shirt. Others believe it may have been influenced by Chinese clothing styles, or even American military uniforms worn during the Spanish-American War.
In summary, while the name "camisa de chino" suggests a Chinese origin, the shirt's actual origin is unclear and likely a combination of influences from different cultures. It is important to note that the term is not intended to be offensive or derogatory towards Chinese people.
