National People's Congress vice-chairman Cheng Siwei receives a warm welcome from students and staff at Lingnan University yesterday. He told the students they should 'think systematically and innovatively' as the future was in their hands. He assured Hong Kong it would not be marginalised if its people stayed vigilant and strengthened its advantages. Mr Cheng, who was educated in Hong Kong, fielded questions ranging from Sino-American economic ties to teaching styles.
