"Why 70?"
It is 70 in order to ask such a question.
This work can be divided into two parts.
In the first part, until the count to 70, the camera is fixed on the green leaves of the cabbage.
In the second part, the camera is attached to my body, faced toward a building and recording while I stand up and sit down 70 times each.
If the former represents the object,
The later represents the action.
The relation between the former and later represents the subject
And the limitation of the work of 70 produces the shell of significance.

This is the representation of the subject's significance production process of the object.

In addition, this is a method of memory of the my most painful period of time, that lasts the longest, cold like a bronze statue.
