Through careful observation, I found that due to space limitation, many of the domestic space is fragmented from the living room, included kitchen, laundry space and bathroom. With the domestic needs fragmentation, public pathway become space for domestic activity as well, such that if we define a boundary of a house by activities, the border is extended. The boundary of houses is redefined. It expands with activity ,and thus time.
Besides, the fragmentation encourage the usage of pathway of villagers and eventually boost human collision of people in pathway and turned it into a communal space.
