I will second Leo’s advice about trying tea at teashops. Often I will get a variety of tiny amounts of tea just to try. If I don’t do that, and I just blindly buy 50g or more of something, I may be disappointed, and then stuck with tea that I don’t want.
One of the difficulties of buying in China is that there are so many variations of one type of tea. For example, Huangshan Maofeng has a million different varieties, some of which may look and taste totally different.
