Chinese contributions to the United States of America

One of the major contribution the Chinese have
made is their work on the Transcontinental railroad.
A contribution that is a big part of our lives now is Chinese food . This is because just about everyone has had Chinese food.
So if These immigrants hadn't come we wouldn't have Chinese food. Another contribution they have made is the traditional Chinese fighting style of Kung fu. Which is the basis of many action movies we see now.
