The flexible system of association promotion - the association promotion system provides later development support to the unit of association, which is co-ordinated with the unit of association after more than one year of ordinary unionization, (the general union phase, where hen-tai provides supervision and supervision, where the unit of association is required to pay administrative fees, as detailed in the "selected type of wisdom of the union"") if both parties are satisfied with the cooperation, the unit of association may apply for a "red partnership" whereby the unit of association entrusts the company of hen-tai with direct management of the store, and hen-tai is involved in the completion of the business and no further administrative fees are charged. After a "red phase" of cooperation between the two sides, either side can propose a "selected cooperative relationship of wisdom" in which the "hing tai company" injects funds into the union store to improve conditions or expand the scope of operations, etc., with a view to achieving a better and better operation!
