What if the Home Visit Permit is valid for less than half a year?

Home Visit Permit is a passport for Hong Kong and Macao residents to travel to and from the Mainland. Hong Kong and Macao residents' travel permits to and from the Mainland, commonly known as Home Visit Permits, are issued by the Exit-Entry Administration of People's Republic of China (PRC) for residents of the Hong Kong Special Administrative Region and the Macao Special Administrative Region with China nationality to travel to and from the Mainland of China. On March 8, 2008, at the fourth plenary meeting of the first session of the 13th National People's Congress, China announced the establishment of the National Immigration Bureau (managed by the Ministry of Public Security). The National Immigration Bureau was formally established on April 20 13 18, with the brand of People's Republic of China (PRC) Exit-Entry Administration. Hong Kong and Macao residents' passes to and from the Mainland are issued in the name of People's Republic of China (PRC) and People's Republic of China (PRC) Exit-Entry Administration (that is, the National Immigration Administration, one institution with two brands). On February 1 1, 2065438, Hong Kong China Travel Service (CTS) announced that in order to improve the efficiency of the accreditation service, CTS officially launched the new reservation system on March 15, 2009, and handled the "Mainland Pass for Hong Kong and Macao residents" (commonly known as "Home Visit Permit") and other related businesses.
