Can I take away the porcelain for drinking tea in general hotels?

That's not allowed, because they are all high-value goods, and hotels can't let people take them away casually. If it is a towel or handkerchief with the hotel name printed on it, you can take it away, because it is a low-value commodity, and high-value commodities with the hotel name are not allowed. This is a etiquette convention. thank you
