Out of major space technologies:
Heavy lift vehicles - China has lead in and much more experience and years more developing, building and using than India.
Manned space flight - China has lead in and much more experience and decades more doing than India which hasn't even done it once yet so maybe not just decades but possibly will be centuries or millennia etc more experience than India assuming India ever passes this.
EVA - China has lead in and much more experience and years more developing, improving and doing than India.
Docking tech - China has lead in and much more experience and years more doing than India.
Rocket engines - China has lead in and heavier thrust, more types, both solid and liquid fuel technologies (cryogenic which India brags a lot about even though it's so basic and common) compared to India's very low tech engines and only a few types.
Testing facilities - China has lead in and much more investment over decades longer than India.
Orbiting and satellite warfare technologies - China has relay types and movable types which India lacks still. Take a look at this link.

For a long time China has been improving satellite warfare tech and they can all take advantage of extremely difficult lagrangian orbits which Indian ones are not yet capable of. Again years more experience in doing. Decades more experience in development and testing. American and Chinese satellites have been at war maneuvers in space for years now. Indian satellites don't even work well while ours are performing maneuvers only two nations on earth can do currently.
Lander technology - China has performed 3 major and difficult soft landings with success. India has yet to perform one successfully.
Rover technology - China has successfully operated 3 rovers with two on the moon and one on Mars. India has zero.
Space station technology - China operated space lab Tiangong 1 for nearly 7 years before deorbiting that trial station and starting the current space station program which has many modules already and several missions. India has not yet deployed even a space lab with one small module.
Launch facilities - China has much more launch facilities than India and building more than India at a faster rate than India. It also is developing several ship launchers with already many built and used for years while India has yet to develop a single ship launcher.
Spacecraft - China has Shenzhou spacecraft developed from Soyuz, since 1999. India has yet to develop a single spacecraft. It is already more than 20 years behind China just on this. Shenzhou is much larger and more modern and advanced than Soyuz despite being developed using Soyuz technology purchased from Russia. But this is 22 years old as a launched spacecraft but over 30 years old as a piece of technology that was developed back then. China now has flown the Next Generation Spacecraft (one of the world's most modern and advanced multi crew spacecraft) two times successfully once in 2016 and once in 2020 with unmanned trials and landing them back safely inside China. India only has powerpoint spacecraft programs.
Deep Space Network - China has it's own since 1980s and India to this day still requires US and European assistance with deep space network and borrow others to perform any space mission that requires DSN.
All of these are the main components of space technologies and China is ahead of India in development, building, testing, and using. India offers few launch services and no one is buying Indian space launch services these days, only one customer every few years. Not even Indian government buys many Indian space launch services.
Private or non-national space sector, China has over 10 organizations involved and have been launching and developing multiple techs on their own for years now. Some affiliated with government have access to national space technologies and suppliers but many are doing it all themselves. It is young but it is far ahead of India's in developing and doing.
Oh and Beidou/Compass is many times more advanced than the Indian failed project GNS which is not even functioning properly while our coverage for Asia region is superior to even GPS of US with even more accuracy and allows for active multiway direct communication with even ground commercial user level which GPS still does not yet offer.
India has not even been able to develop something similar to Longmarch 3 level, it will need decades more to get to Longmarch 7 and Longmarch 5 level.
