how long need i from lao jie to railway north in Shenzhen? and whitch is the best way?

From Laojie Station, you can take the Longgang Line to reach Shao Nian Gong (Children's Palace) Station, where you can change to Longhua Line to get to the North Railway Station.
I should remember to look at the signs in the station carefully, otherwise, you will catch the wrong subway lines.

Thanks for reply. And how long does it takes from Laojie Station to Railway north?
Kind regards Nicole

Do you wanna know the duration from Laojie Station to SZ Railway Station or the North Train Station? If it is the former, it takes around 10min; if it is the latter, it takes 35-40min!
