In the schematic diagram of cherry grades in the southern hemisphere, jumbo (abbreviated as J) is usually used as the standard unit of high-quality cherries. The standard fruit diameter of J grade is 26-28mm, JJ/SJ/XJ is 28-30mm, and JJJ/XXJ is greater than 30mm. Similar parameters can be found on the label of the imported original box.

J's jargon reads "ditch" instead of "knot", and single ditch, double ditch and triple ditch are the standards to distinguish the quality of cherries. The more numbers of "J", the bigger the cherry. The cherry in Sangou is the top grade.
