You can burn steamed buns for Nanyue.

What you want to ask is whether you can burn incense for Nanyue? Yes, you can.

Many friends can't go in person because of various reasons such as time and distance, so the local incense shop has developed a business of burning incense for customers instead of pilgrims to worship Buddha in Hengshan to help them achieve their wishes.

As long as your heart is pious enough and your faith is firm enough, your wishes can always be heard.
