Shengda's creative online game for 2007, "Tui Tui Xia," will be undergoing internal testing on January 8th. The official statement says that the number of internal testing accounts is limited, and applications are now closed. However, it is actually still possible to apply for an account using a specific link, even though there's no visible entry point for applications.
