No, you can't say 'tea picking' as you can see it is not done by bare hands anymore and I believe it is far harder to hold up these big scissors with the sack. (You can compare by cutting your hedge straight on top with shears).
Indeed it is only the top leaves reaped in the morning that has the most flavor but these girls are working from 8h in the morning till 16h in the afternoon as you can see in the full sun.
Many of the tea-gardens in Munnar are not used anymore as they suffer from a fungous disease and those that are still healthy have to be sprinkled with chemicals.
This harvest is only the start of a long process that it has to go before it can be used for tea.
So ... Tea from her to you.
