I was an exchange student. In 2014, I got the opportunity to study at Southern Institute of Ecology (SIE), Vietnam Acadamy of Science and Technology and International Center of Tropical Highland Ecosystem Research (ICTHER) for 1 month. I went to field trip at Mekong Delta & mangrove and collected soil sample in mangrove forest to analyze the pollen in soil. The pollen will tell our about the past of this area. This field trip taught me to have patience and open mind for learn new thing outside classroom.
