"To be honest, all citizens of Guangzhou and Shenzhen have a headache for the Guangshen Expressway. Other than the off-peak hour after 23:00, the road is solid with traffic." Lin Hui said, on the two Conferences (the NPC and the CPPCC), they agreed the necessity to strengthen city-to-city cooperation between Guangzhou and Shenzhen. Although they are only 150 kilometres apart, people have to spend 2–3 hours on the highway. Delegation representatives of Shenzhen city started to mention to cut the price in 2003. Shenzhen representatives have requested a reduction every year since 2007.
