First of all, I'm not from Qingdao, but from Suzhou. But I also had double eyelids. In 2008, it was 2000 yuan. Later, in 2009, my friend cut the corner of his eye and spent 5000 yuan. The price of opening the corner of the eye is similar to that of double eyelids. European-style double eyelids are popular now, which are very wide and very European and American. I hope my answer is helpful to you.
