OVER 30,000 passengers took Metro Line 1 as Hangzhou's first Metro line started trial runs yesterday.
The test runs will last four days and the city has handed out 600,000 free-ride coupons to residents, according to the Metro operator.
Most of the passengers were happy with the experience, saying the Metro system is comfortable, quick and easy to use.
However, some said the guiding signs are too simple with only an arrow and Chinese word for "out" marking exists, while the maps are not easy to find on the subway wall. Some suggested adding the names of landmark buildings at each exit.
"The map in the inquiry machine is too small for me, not to mention for old people," Mao Jiajun, a seventh grade student, said.
"A measure should be put beside the ticketing machine instead to gauge children's heights, as it takes too much time after the kids are found to be above 1.4 meters and have to line up again to buy tickets," Shen Guoqiang from Hangzhou Sightseeing Bus Center said.
Some suggested that the height measures be made from cartoon figures to attract kids to measure themselves.
