2003年港澳個人遊（自由行）政策實施之後，間接造成大量無香港永久居留權嘅中國「雙非孕婦」喺香港分娩。2001至2011年，因此獲得居港權嘅「雙非嬰兒」超過37萬人。由於細路喺香港出世就可以擁有香港永久性居民身份，由此享有教育、醫療、房屋等香港社會福利，造成資源分配唔公平，引起香港社會強烈不滿，市民多次上街示威抗議。
In 2003, after the implementation of the Individual Visit Scheme (Individual Visit Scheme) policy for Hong Kong and Macao, a large number of Chinese "double non-resident pregnant women" who did not have the right of permanent residence in Hong Kong gave birth in Hong Kong. From 2001 to 2011, more than 370,000 "double non-resident babies" were granted the right of abode in Hong Kong. Since children born in Hong Kong can have Hong Kong permanent resident status, and thus enjoy Hong Kong social benefits such as education, medical care, housing, etc., resulting in unfair distribution of resources, causing strong dissatisfaction in Hong Kong society, citizens have repeatedly taken to the streets to protest.
