單維彰老師是個登山愛好者，我確信這樣的體驗會的確會讓人一生難忘吧
Dear Chi-Hsin and fellows:
The Grand Circuit trekking trip in Torres del Paine is done.
We are so proud that we went all the way to literally the other end
of the world and complete the hiking.
On the 8-day trail which covers at least 120 kilometers,
we have seen great glaciers, mighty mountains, beautiful ponds and
magnificent lakes,interesting animals and lovely flowers.
But we also have to cross a high pass, to cut through bitter-cold gusts,
to ford freezing torrents, and above all, to fight our homesickness
and occasional psycological weakness.
The hardship is done, and the reward is a lifetime memory.
We are back to the nearest town, Puerto Natales, 1.5 hours ago.
The team will be dismissed tomorrow, and we will start the return trip
individually.
We will share with you stories and photoes later.
And we miss you all.
