Since the suff event of Coral Bug, I seemed never used QQ with displayed IP. Recently I found this DIY version of QQ by a madman, which can automatically detect and install the latest version of the Coral Bug QQ installation program. It has nice functions and I haven't encountered any errors. Compared to Rainbow QQ and Drifting Cloud QQ, I feel this one is better.
Another advantage is that you can customize the installation of QQ, removing those functions that you don't use.
