I'm planning to visit Heilongjiang, not for the city tour but to the trading place where Russia,China meet.

there are several such trading places in the province and the one at Suifenhe is largest. Where are you leaving or which city are you going to depart in China? Then i can tell u the transportation to arrive.

Thanks Elina,

If I depart from BJ.. is there a connecting flight to HLC.. or train service?

You mean from Beijing to Suifenhe?
If so, I am afraid that there is no direct train or flight between, so you need to transfer.
You can take bullet trains to Harbin first and then change trains to Suifenhe. Or you can fly to Harbin and then change to trains.

Thank you Linda,

In this case I shall start off in BJ, an route to Harbin take a train to HLJ.
What is the best months to travel. I'm a Singaporean not use to extreme cold countries.

pls advise.
