We may have to be proud so many times then if we do that every time we have such improvement.
I will not make that statement of nothing to be proud of for beating japan in payload. Despite Japan not being able to send a man to space. Their heavylift is enough to send a bigger, heavier module for ISS effort. Some of Japan sensor and deep space exploration is still more ahead of China due to their heavy rocket load. Once YF-700 boaster debut, it will have a lots of application for deep space, lunar manned mission and space station effort.
Yes, we still need to work hard to go far ahead but every step ahead China space agency make is worth the applaud to them and all Chinese to continue working hard for China space exploration.
