Maybe add a 50 yuan! If so, I suggest you buy mutton kebabs, sausages and vegetables in large packages, which are resistant to roasting! Such as leeks, potatoes, corn, eggplant and so on. If you can, buy some strings of saury and fresh oysters! Also buy barbecue sauce and cumin, salt and pepper and other spices! Don't bother to buy a good one! Also, if you rent a grill and carbon, it will be very expensive! Try to bring your own!
