If you can find TOR nodes, so can the Chinese government. They can then just block these addresses.
Furthermore, the great firewall is quite advanced, they use machine learning techniques to detect patterns, so even if it is TLS on port 443, they may be able to detect it after they have gathered enough traffic. There are workarounds of course, but it is not as simple as just using a TLS tunnel.
