How to go to terminal 1 from termonal 2, also need to cache bus 806 at terminal 2 with some lugages.

There are free shuttle buses running between terminals. The shuttle bus runs every a few minutes and it takes 15 minutes between T1 and T2.
Pick-up points:
south side of Gate 6, Departure Hall, T1
north side of Gate 1, Arrival Hall, T2
Hours: 06:30-23:00
Frequency: every 15 minutes, 5 minutes in peak hours
Well, the bus 806 is at terminal 1, not T2.
