Is there a hook for Chinese character seven? Chinese characters have gas hooks and strokes are vertical hooks. Moreover, the hook of the seven-character vertical hook is written upward. When writing seven-character qi in print, there must be a tick. For example, the seven characters written by calligraphers have their own characteristics and styles. For example, cursive script and official script do not necessarily have a tick. However, it is not necessarily a tick to write the seven-character qi formally.
