Another thing to note.
Its very bad to say TungTing mountain*S*, because there is only one place with that name, although the Deer Valley/Alley area do contain many peaks, there is only one with the name TungTing there.
About the attitude of the Tea Gardens, TungTing Mountain's peak is rated at 740m.
But on the west side of the region, there are many gardens with attitudes >800m
especially around the Phoenix mountain. With some gardens higher than 1000m. 600m is really an understatement about the height of the tea gardens there.
However I would say that attitude doesn't mean that much in terms of quality. The micro climate/terrior of the garden, harvest condition, and manufacturing makes a great difference.
Here are some pictures from the local elementary school.
