Overland backpack to Europe

[Yellowtravel]

I am looking for like minded people to travel overland to Europe and flying back to Singapore.

Planning to take a direct bus to southern Thailand and slowly making my way to China, before taking the trans-Siberian rail to Russia and the rest of the EU.

Plans to do so in December, and arriving in China for CNY before the rail trip.

Those who have done it before, feel free to share your inputs.
