Chinese Astronomy Recorded Comets and More

I was astonished when I attended a museum showing of Chinese astronomical artifacts, which toured a couple years ago to the Midwest.
One exhibit displayed a chart of the many different types of comets – 27 in all, according to an ancient chart. Their close observations noted not only the size and shape of the tail, but any discernible differences in the core of the comet. You can view this chart online at http://hua.umf.maine.edu/China/astronomy/tianpage/0009H_comets6563w.html
Comets were called ‘broom stars’ (tui xing), named after their tails, which they duly noted always pointed away from the sun. They had no idea what the cause of that orientation was, but they made copious notes of that and other details. The Chinese are believed to have made the first observation of the legendary Halley’s comet in 240 BC. On its return in 530 BC, they noted that “In September, it was one degree to the northwest of Xiatai ( a star in Ursa Major).”
According to the folks at China.org, the Chinese noted in addition to comets, the lunar and solar eclipses (the ones visible in their region), novas, and more. They invented astronomical clocks, and a type of armillary showing the relative positions of the planets. [The Greeks and the Arabs also had armillaries.] Yet astrology as we know it today or even in medieval times was not part of Chinese astronomy.
