At the top of each item page, you can see the approximate HSK level of the item.
The HSK has nine level in total numbered 1 to 9, with the last three 7-9 being grouped together.
Here are the details for how the HSK level is calculated for each item type.
To compute the HSK level for a sound, we assign the lowest HSK level which has a character that contains that sound.
To compute the HSK level for a component, we assign the lowest HSK level which has a character that contains that component.
The HSK level for most characters comes directly from the official HSK list.
However, if we have a character that is not contained within that list, we will mark it as having HSK level
The HSK level for most words comes directly from the official list.
However, if we have a word that is not contained in that list, we will mark it as having an HSK level equivalent to the highest HSK level of the characters within it along with a
+ sign to indicate it is not within the official level itself.
For example, the word 因果 yīnguǒ is not in the HSK word list. The character 因 yīn is in HSK level 2, while the 果 guǒ has HSK level 1. So we mark the word as having level
2+, as that is the highest HSK level of the characters within it.
