There is plenty of time in a week, and several places worth visiting:
1, Chimelong Happy World (quite exciting, suitable for young people)
2. Sun Yat-sen Memorial Hall and Chenjia Temple (understanding history and Lingnan culture)
3. Sun Yat-sen University (Guang Zhouta is nearby, and you can also visit the Pearl River in the evening).
4. Yuexiu Park and Baiyun Mountain
Nothing else is particularly interesting.
