Kuo Chun-yin opened a 'bank' in a village in the lush fields of Central Taiwan's Changhua. However, this isn't the ordinary bank where cash and financial products are managed. Kuo's bank is a place where trees are deposited. Its primary mission is to promote conservation and help endangered plant species through reforestation. His ideas have touched many across Taiwan. His newest branch is in the nation's remote outer islands of Penghu and Matsu. This is how Kuo gives back to his native land.
