Traveling in Hong Kong

I had wanted to make this shot for a while but haven't had the right moment for it until yesterday, when I had to take the last train from Kowloon Tong to Mong Kok East, cause I missed the last train leaving Kowloon Tong to Tai Po. I could finally take the shot without having too much people in the way, actually the train was pretty empty. Luckly did not missed the last train back to Mong Kok East so I could take a small bus or as they call it in Hong Kong a Wen Chai to Tai Po. 24 hours a day those wen chai ride to certain areas, also the cost of traveling with them are not that expensive. Close to the Mong Kok train station there are allot of these busses also at the end of the Ladies Market there are these busses, there is pretty much a whole central area for those busses there. I could either take the bus going to Sheung Shui and stop at Tai Po which have a busstop at the end of the Ladies Market. However several streets further close to the Mong Kok MTR there is a one that directly goes to Tai Po.
I took the bus going directly to Tai Po which is easier because it got certain places it stops for everyone, while other busses you have to ask it to stop at certain places. You often might hear people yell " Stop at the end of this street" in Chinese. However might sound rude but it is bit of the culture riding these busses. Also the bus goes throught a tunnel through a certain mountain however I don't know which mountain it is. However I recognize this tunnel from a movie called Legend of Speed 2 where two cars race against each other. Above the numbers in red is actually the speed of the bus, they actually show how fast the bus is riding also give a warning signal when it exceeds a certain speed.
Would be interesting if I rode in a big bus and sat on the top level and show some pictures. However sitting in the back of this small bus I could still make some intersting pictures in this tunnel. I still need to check out the normal busses how they all rides and if they are more expensive or not.
