Nonetheless, the physical environments of the old housing is limited and mostly revitalized by the private owner which the outcome can be very much uneven from the architecture point of view. How to guide this process without ruining the positive urban phenomenon during the regeneration, is also very challenging.

4. PROPOSING DESIGN APPROACH

Culture and historical cities like Xi’an, must be a collective joint of all historic layers in the contemporary urban spaces. Regarding to inner city regeneration, a culture sustainable design approach need to be adopted to guarantee the diversity and compactness of the city. Culture sustainable design approach can involve the promotion of culture-based events and attractions along with encouraging the development of higher quality housing and retail, and the attraction of professional businesses to the area. It is highlighting the value of the matrix of local cultural, and actors to improve the physical environment and reconstruction of local cultural network\cite{Miles_2004}.We count on the cooperation of multi-aspects will form a solid foundation in participation and fulfillment of urban design and planning.
