As a typical form of informal economy, township farm has filled the vacuum and defect that the formal economy has not touched. Market participants do not necessarily aim to satisfy the basic need to buy fresh produce; the combination of hanging out, meeting friends, wandering crowds and the atmosphere of freedom makes this place a uniquely attractive place of daily life, an indispensable means of social interaction. This "informality" gives it different characteristics from conventional commercial buildings, that is, the field building should have both "indoor and outdoor", and maintain a fuzzy boundary effect. As a public place with the most "fireworks atmosphere", the gathering field should be able to comply with the native relationship of the township, rather than a forced "foreign body". It should be a "real place", not too "precious" and "reserved", to create a friendly and welcoming atmosphere, and to create a community that promotes the mixing of non-agricultural and agricultural populations.
