The entire entertainment industry in Hong Kong has started to decline, and the once proud "Hong Kong made" label suddenly lacks confidence. Meanwhile, after collaborating more closely with Hong Kong, mainland entertainment professionals have broadened their horizons by earnestly studying specific filming techniques, performance models, complex star-making processes, as well as macro production philosophies and entertainment operation modes from Hong Kong. The film and television industry on the mainland has thus developed vigorously and colorfully. The mainland possesses abundant natural outdoor shooting resources, a large number of inexpensive background actors, powerful investors, and the government also strongly supports the entertainment industry, with massive construction scales for film cities... If one wants to shoot a movie or TV drama, where else would they go if not the mainland!
