They can also book on the Beijing Municipal Marriage and Adoption Registration Services Website (www.bjhysy.bjmzj.gov.cn) or the Beijing Municipal Civil Affairs Bureau website (www.bjmzj.gov.cn) from July 7 to August 5, he said.

Foreigners, overseas Chinese and citizens of Hong Kong, Macao and Taiwan, can also benefit from the service.

Chinese couples are keen to tie the knot on an auspicious date. August 8, 2008, or 8-8-08, is more than just a date: it marks both the opening of the Beijing Olympics and is considered a lucky day for marriage with all the number eights in the date.

Eight is the most auspicious number for Chinese who believe it brings fortune and happiness.
