This thermal evaporator was broken last term, and I felt the end of the world at that day.
To take the system apart only needs few hours, but to put it back to working condition needs several months.
After we put hands together, we made some movements. Though it is a slow progress, it is on the right track.
Keep my fingers cross for the next step！
