The 9th China International Garden Expo (Beijing) opened on May 18. On the first day of the event, most visitors rode BJL14 which started trial operation on May 5.
To handle the expected large passenger flow to the grand event, emergency exercise was conducted at every station of BJL14 to enhance their capacity. One day before the event commenced, May 17, temporary signage was posted at Garden Expo Part station of BJL14 to provide convenient guidance to the passengers.
