i put 4 days bus tour too. it's really easy...the visa officer only asked 3 questions to my dad..(1) are you still working? (2) what's yr occupation? (3) when will you go back China...later, i want to show him the bus tour booklet... he said no... (he is a 30-yr-old man. i heard he was the easiest one to pass).. it was only 5 minutes interview...finally, he said:"i approve your visa".... BRAVO~~~
