Premier Wen Jiabao was kept busy yesterday with official engagements as he concluded his visit to Egypt and left for Ghana. But there was a light moment when a six-year-old martial artist reminded Mr Wen of his grandchildren. Mr Wen made a surprise call to a troupe of performers from China who appeared at a gala celebrating Sino-Egyptian diplomatic relations. Stealing the limelight was Liu Qimeng, who started practising martial arts at the age of three. 'You are the same age as my grandson,' Mr Wen said as he embraced the youngster.
