Should I apply for visa now, or should we wait until we are closer to the time of travel?

The Chinese visa is generally valid for 3 months from the issue date to enter China. Please apply for your visa within 3 months of entry into according to your travel itinerary, and avoid expiry of visa, or extra cost of urgent fee due to lack of application process time. Please also decide the duration of stay in China. The permitted duration of stay of Chinese visas are generally up to 30 days. If you need to stay longer, it is suggested that you contact the Chinese Embassy before making the application or ask your travel advisor for more information.
