According to my knowledge, the Biyang Bamboo Forest () in Bijie City, Guizhou Province, is open to visitors. However, please note that the opening hours and tickets prices may vary depending on the season and special events.
As for your second question, as a popular tourist destination in Guizhou Province, Bijie City offers some ticket discounts or promotions specifically for tourists from Guangdong Province. For example, visitors from Guangdong can enjoy a 10% off admission fee with proper identification (such as an ID card or residence permit). But please check the official website of Biyang Bamboo Forest () or contact them directly to confirm any special deals or promotions before your visit.
Please also note that ticket information and discounts are subject to change, so it’s always best to verify this information before visiting.
