Drinks in Hong Kong

I really love Hot Yun Yeung (mixed coffee & tea).

But sadly, this cup doesn't look good.  You can see from its colour.  Coffee:Milk:Tea ratio is not right... Yea... and the tea man puts so much sugar..  What is your ratio? Any suggestion?

Hot Yun Yeung is a mixture of coffee and milk tea, which is commonly found in Hong Kong tea houses and Dai Pai Dong.  In general, the ratio of coffee and milk tea is 30% to 70%.
