Omg these are some of my top guesses too
For Hao I also like Libra and Scorpio asc the best although a lot of people see virgo/pisces which also fit but I like Libra because air rising, he'd be ruled by his Leo Venus in the 11h, Taurus moon in the 8h and most of all his Jupiter in Gemini in the 9h!!, also pluto/Chiron in the 3h and he often talks about having been a difficult teen and mercury in the 10h which makes sense, not so sure about mars in the 10h tho, also 8/9/5h synastry with Hanbin
