About 10,000 young people from south China's city Shenzhen and the Hong Kong Special Administrative Region (HKSAR) on Sunday celebrated the 10th anniversary of Hong Kong's return to China in Shenzhen.

The celebration, said to be the largest celebration of the anniversary held on the mainland, is co-organized by the Shenzhen government and the HKSAR government.

Participants include 5,000 Shenzhen-based university students and about 5,200 Hong Kong youths from 115 organizations and communities, of whom 1,000 are on their first trip to Shenzhen.

Most of the young people from Hong Kong came by bus through the newly-inaugurated Shenzhen Bay Port (or Hong Kong-Shenzhen Western Corridor), the fourth border crossing for vehicles between Shenzhen and Hong Kong.

They visited the city museum, universities and high-tech districts, attended forums and perform hiphop dances, karate, sword play and fashion shows.

Later Sunday, they went to a gala attended by celebrities from Hong Kong and the mainland. With performance of dozens of famous singers and dancers from the two sides, the gala was watched through live show by Central Television of China and local television stations in Shenzhen and Hong Kong.

In Hong Kong and the mainland, celebrations have been held to mark the 10th anniversary of Hong Kong's return. In Harbin, capital of northeast China's Heilongjiang Province, residents displayed a 1,000-metre-long painting to mark the occasion.

Sunday's celebrations in Hong Kong began with a flag-raising ceremony, attended by more than 1,000 people, including Chief Executive Donald Tsang, and ended with a grand fireworks display in the evening.
