The Chinese food you're referring to is Fortune Cookies.

While the exact origin of fortune cookies is debated, the story about Makoto Hagiwara is a popular one. However, it's important to note that there's no concrete historical evidence to support this claim.

The story goes that Hagiwara, a Japanese American landscape designer, worked at the Japanese Tea Garden in San Francisco in the early 20th century. To deliver messages of thanks to customers, he started folding small cookies with paper slips inside containing aphorisms or messages. This story is often cited as the origin of fortune cookies, but it remains unconfirmed.

The true origin of fortune cookies is likely a blend of influences from different cultures and periods, with its roots possibly stemming from Japanese "tsujiura senbei" (fortune crackers) and Chinese "yù pèng" (predictive candies).

Regardless of the origin, fortune cookies are a beloved and iconic part of the American Chinese food experience.
