A survey was conducted in Chengdu, China, on some families of two generations living together in a condominium, with a view to clarifying their lifestyle of and consciousness about living together while investigating how the residence space was used and what consideration was paid to the elders. The results of the investigation are as follows : (1) Two generations made it a point to have a meal together at least once a day, which shows that the communication between the two families is closely maintained. (2) Regarding the housework such as cooking and washing, there seems either of the two cases of two families sharing the work or one family doing it more often than the other. In either case, parents tend to pay much more for living together so far as the finances go. (3) Over 60 percent of the two generations are in favor of living together, citing as benefit the security and expectation for mutual help on the part of parents as well as the material pluses and convenience to gain from living together with parents on the part of the younger generations. On the other hand, the minuses cited by both generations are mostly psychological in nature such as, for example, their daily communication becoming stressful on account of the generation difference.
