Millions of Chinese Muslims across the country celebrated the tradition of Corban on Tuesday and Wednesday.

In northwest China's Ningxia Hui Autonomous Region, 76-year-old Liu Wenming attended a religious ceremony at the Nanguan Mosque in the regional capital, Yinchuan, Wednesday morning, along with some 10,000 Muslims.

"My son, daughter and grandchildren will come from different parts of Ningxia to have a family lunch with me. Then we will visit other relatives and friends," said Liu.

In Qinghai Province, also in the northwest, many Muslims began to gather at the Dongguan Mosque in the provincial capital Xining before 8 a.m. Tuesday. By 9 a.m., roads outside the mosque were packed with pious Muslims.

Ten ethnic groups in China, including Hui, Uygur, Dongxiang and Bao'an, celebrate the annual festival -- but they celebrate it on different days. Some celebrated it on Tuesday while others celebrated it Wednesday. The timing depends on each ethic group's tradition.

The Corban Festival, also known as Id al-Gurban, is a major Islamic festival that is meant to demonstrate believers' faith and obedience to Allah. People slaughter livestock and divide the animal into three parts.

One part is to be eaten by the family. Another part is for relatives and friends. The third part is for charity.

Migrant workers from northwest China's Xinjiang Uygur Autonomous Region returned home this month in time for the festival.

Eighty-seven migrant workers from Shule County returned home in early November to join their families in celebrating the joyous occasion.

Additionally, the regional government organized a reception on Tuesday afternoon, during which Zhang Chunxian, secretary of the regional committee of the Communist Party of China, met representatives from all walks of life.

At the end of his speech, Zhang greeted the Muslims while speaking in the Uygur language, which received warm applause.

China has more than 20 million Muslims. They mainly live in Xinjiang, Ningxia, Gansu, Qinghai, Yunnan, Shaanxi, Inner Mongolia and Henan.
