Cookies used to be a high-sugar and high-fat food. Although cookies are also a kind of biscuits, they contain butter and are more delicate than ordinary biscuits. Cookies, from the English transliteration of Hong Kong, meaning "tiny cakes", were first invented by Iran. In 1980s, cookies were introduced to China from Europe and America, and set off a craze in Hongkong, Macau, Taiwan Province and other places at the beginning of 2 1 century, and then they became increasingly popular. In Europe and America, every holiday, in order to show their love and respect for their relatives and friends, girls will go to the biscuit workshop and bake attractive biscuits for them under the supervision of their tutors. But in China, things have changed. People choose to order some cookies online and give them to the other half in exquisite packaging.
