Disclosed are mortise and tenon joint structures for Chinese characters formed by building members having the same or different configurations, and a method for inputting Chinese characters by using the building members. The Chinese characters are de-structured such that each Chinese character consists one or more radicals which are formed by the mortise and tenon joint structures or variants thereof. The variants of the mortise and tenon joint structures are formed by shift, rotation or combination of shift and rotation of the building members of the mortise and tenon joint structures. This establishes an inputting method between the Latin letters and Chinese characters.

Disclosed are a Chinese character structuring member, a system of mortise and tenon joint structures of Chinese characters formed by the Chinese character structuring member and a method for inputting Chinese characters. An entity component of Chinese characters includes the following three structures: an entity component provided with a connecting mechanism at a middle and/or one end or both ends of the entity component configured to join with other entity components of the Chinese characters; an entity component provided with a connecting mechanism entity component extending from one end of the entity component to the other end of the entity component without exceeding the entity component of the Chinese characters; and an entity component provided with at least one connecting mechanism on the entity component that includes a plurality of sub entity components connected end to end and rotatable at the joint.

A kit defines an educational apparatus and includes multiple blocks. At least some of the blocks have a length equal to a unit length multiplied by an integer from 1 to 10, and includes, for each length equal to an integer from 1 to 10 multiplied by the unit length, at least one block. The blocks bear indicia identifying the integer corresponding to the length of the block.

A system and method for training and guiding cleaning professionals in the use of janitorial and cleaning products, includes specifically configured labels for the products and a variety of visual and other support materials provided via a website that are configured to facilitate training of the end user. The support materials are complementary to the labels so that after the end user has been trained using the visual support materials, the labels reinforce the training and provide on-site reminders of proper and effective use of the products.

A block teaching aid for learning a language, includes: an individual letter block made individually for each of individual letters forming a particular word, wherein the individual letter block has an appearance corresponding to a shape of a corresponding letter or at least includes the shape of the corresponding letter to allow the corresponding letter to be cognitively identified; and a block storing board defining an accommodation space to accommodate individual letter blocks that form the particular word, and constituting a frame to store the individual letter blocks therein, wherein, when the individual letter blocks are coupled and assembled with each other, they match with each of partial shape elements to make a three-dimensional shape corresponding to meaning of the particular word.

This invention describes a 4-dimensional periodic table of elements (4D PT) based on the 4 known quantum numbers of the atomn (principal), l (azimuthal), m (magnetic) and s (spin)which determine the 4D Cartesian co-ordinates (n,l,m,s) of a 4-dimensional cubic lattice. Since the four quantum number combinations of each element are unique by Pauli's exclusion principle, each chemical element occupies a different vertex of this lattice and has a unique location in 4D space and hence in the periodic table. The 4D PT of elements extends to chemical molecules and compounds by adding coordinates of individual elements into composite coordinates of molecules and compounds in a larger expansive PT. The higher-dimensional table of elements and compounds can be represented in any digital media or print media as 2D charts or cards. The 4D PT #can be physically built as 3D model kits comprising nodes and connecting struts or 3D blocks or connected 2D panels.
