Around 1 to neg 8 daw. Mid Feb ang Chinese spring festival. .
that's without the windchill factor pa! don't be fooled. Beijing can be colder than say, vancouver or montreal because of the winds which can reach 20kph sometimes. add to that the haze (or smog) which blocks out the sun. 80% of the people here wear down jackets/clothing.
Beijing is pretty much a walking city. Malalaki din ang tabas ng Blocks. kaya wala ka masyadong makikitang mataba or bundat ang tyan.
Just imagine them having hordes of jeepneys and tricycle. chaos na yun. mas maganda , sa opinion ko, na walang tricycle at jeep sa pinas. mas aasenso tayo.
As for colds, you can always take Gankan. very good for the flu/cold . 2 days lang wala na. hehe.
I'm currently in Beijing now . I enjoy everything except the trains. lol.
the trains are good. they can bring you around the city. but grabe during peak hours. you'd have to fight to go in. and fight to go out. kapalan na lang ng mukha. kung ayaw nila magbigay, you have to push yourself in/out. hindi pwede hiya hiya. if you have to pat the shoulder of the guy in front of you, you must do so. "switch tayo ng places" lol mas masarap pa ata buhay ng mga sardinas sa lata. 2 yuan lang per trip sa train.
knowing how to speak chinese is a big plus. imagine buying a pair of pants and the price is 1200 yuan. dadaan ka pa sa drama ng pag tatawad. but if your chinese is good and you have a good accent. they give right away, say, 1/10 of the price.
DIY tours are good as long as you know what to do and how to communicate with the locals. they also have some bias pagdating din sa marunong mag chinese. pag turista, big money!
My friends and I went to Mutianyu via a van that we hired. We ended up paying only 60 yuan per person.
