What is the difference between large cymbidium, medium cymbidium and weak cymbidium?
It looks like a cross between Shizhang Hong and Baodao Xiannü. A red-flowered three-star butterfly form of Jianlan (Cymbidium ensifolium), a fine butterfly-type flower, with tall scapes that rise well above the foliage, elegantly arching leaves, large color blocks, lively and vivid; the lower the temperature, the more vivid the flower color. New shoots start out red, are pink-tinged as new shoots, and turn green once mature.

This is the common colloquial way of saying it, and there is no fixed rule, but I suggest we discuss it together and establish a standard.
Large cymbidium - naturally grown, and able to bloom with just the mother, daughter and grandfather three-shoot plant; this can be called a large cymbidium.
Medium cymbidium - grown for one to two years and able to reach the large cymbidium standard is called a medium cymbidium.
Small cymbidium - grown for three to four years and able to reach the large cymbidium standard is called a small cymbidium.
Weak cymbidium - anything that does not reach the small cymbidium standard but is still a shoot capable of continuing life is collectively called a weak cymbidium.
Using the large cymbidium as the standard, the conversion coefficients of medium, small and weak to large cymbidium.
1 shoot of medium cymbidium = (0.6~0.7) shoot of large cymbidium
1 shoot of small cymbidium = (0.2~0.3) shoot of large cymbidium
1 shoot of weak cymbidium < 0.1 shoot of large cymbidium
The coefficient of different generations in a connected plant relative to the front-growth shoot
Under normal circumstances, for a connected three-generation large cymbidium of mother, daughter and grandfather, any single shoot is equivalent to one front-growth large cymbidium shoot.
For fourth-generation and fifth-generation cymbidiums, if they have not been divided before, convert according to the following coefficients
Fourth-generation cymbidium (must have met the large cymbidium standard when young) with relatively sound roots and leaves = 0.6 shoot of large cymbidium
Fifth-generation cymbidium (must have met the large cymbidium standard when young) with relatively sound roots and leaves = 0.4 shoot of large cymbidium
Those that do not meet the above conditions, or are older than five years, can only be counted as one weak cymbidium.
Term explanations:
Natural cultivation: cultivation without heating, cooling, supplemental lighting or hormones counts as natural cultivation.
Special circumstances:
One shoot of Guangdong and Fujian cymbidium is equivalent to 0.8 shoot of naturally grown Jiangsu and Zhejiang cymbidium.
One shoot of cymbidium grown in environments with heating, supplemental lighting, cooling, etc. is equivalent to 0.6 shoot of naturally grown Jiangsu and Zhejiang cymbidium.
One shoot of cymbidium under properly controlled hormone cultivation is equivalent to 0.4 shoot of naturally grown Jiangsu and Zhejiang cymbidium.
One shoot of cymbidium under improper hormone application is equivalent to 0.2 shoot or less of naturally grown Jiangsu and Zhejiang cymbidium.
