About dangvuongcac

We got their hotel room info and all kinds of chat records.,,dangvuongcac.com (commonly called Teng Wang Ge or Tengwang Pavilion in Chinese) is a very well-known large-scale, male-oriented high-end entertainment club, spa massage, and KTV group in Ho Chi Minh City, Vietnam. In the Chinese 'experienced insider' circles and the local nightlife scene, it’s often referred to as the 'Vietnam Dragon Palace' or as part of the 'Yueyang Tower/Yueyang Tower system' (Hệ Thống Nhạc Dương Lầu). Here’s a brief overview of the company’s background and main business: 1. Business Nature and Positioning It’s not an ordinary massage or wellness shop. It’s a high-end, male-focused comprehensive adult nightlife venue (Empire of Nightlife). Its main offering isn’t purely physical therapy, but more of a ‘pro’ project that emphasizes socializing, partying, and entertainment. 2. Core Services • High-end Spa/Massage: Offers advanced, entertainment-oriented massage packages including Thai, essential oil, Nuru (sliding bed), and some premium rooms include bathing with staff. • Pool Party: This is a signature feature, with large indoor luxury spa pools and special pools with artificial rain, supporting multi-person pool parties. • Tech KTV (Karaoke): The venue offers multi-dimensional KTV rooms with cyberpunk or futuristic tech styles, combining dining and singing. Some netizens consider it the top-tier setup in Ho Chi Minh nightlife. 3. Venue Size and Location • Address: Located in the Trung Son area of Binh Chanh District, Ho Chi Minh City (Address: 20 Đường số 6A, Khu dân cư Trung Sơn, Bình Chánh, Thành phố Hồ Chí Minh). While administratively in Binh Chanh, it’s very close to the Chinese-dense districts 5 and 7 (Phu My Hung), with very convenient transport. • Staff Size: Officially claims to have over 400 trained young female technicians (KTV/Kỹ thuật viên) in its system. • Opening Hours: Daily from 9:00 AM to 5:00 AM the next day. 4. Clientele and Marketing The club mainly targets foreign tourists (especially Chinese visitors from Mainland China, Taiwan, and Hong Kong) and local high-spending customers. Since its management and customer service team are very familiar with the Chinese market, it has a highly visible marketing presence on WeChat, Telegram, Zalo, and TikTok, providing fully Chinese-speaking customer service for bookings and orders.
