Can I purchase entrance tickets & show tickets using Union pay Debit card in Guilin?

Places like Elephant Trunk Hill park, Seven Star, Fubo Hill etc accept payment by Union pay Debit card or they only accept cash? Can I use Union pay card for the Li Liver Cruise to pay the hotel or travel agent for booking as well? What about Impression of LieSanjae in Yangshuo, do they accept Union Debit card too? I plan to get a Union Debit card from Bank of China in Malaysia. They said this card is widely accepted in China, better than using credit card. Also, I don't have to carry so much cash. Appreciate your reply, thanks!
