How and when did teacher Hsu join the PMECO?

　　There were eight teachers retired from Shetou Junior High in that year, and I was one of them. I was once the physics and chemistry teacher. I took ecology and photograph classes in the communiversity to fulfill myself since I devoted into ecology conservation.

Do you take charge of any area in the PMECO?

　　I am more interested in restore the butterflies and their living environment, and therefore I work hard on restore birthwort in my turn of duty. By doing that, there are more swallowtails around Cingshueiyan.

Did you ever face any difficulties on promoting the ecology activities?

　　The most difficult thing the PMECO face is how to sustain the spirit of the PMECO. We need more people to get trained and devote themselves to the local ecology.

Reflection：

　　Teacher Hsu is the retired physics and chemistry teacher and is very interested in observing animals and plants. We can feel his resolution to what he is working on and know how much he has done for the ecology.
