Looking for chinese players.

Im part of a Spain-China Friendship association and im looking for chinese players who could forward me information about chinese chess. 

I am currently studying chinese chess and have developed a keen interest in the teaching systems and educational materials commonly used in China for chess training. Many valuable Chinese chess books remain untranslated into other languages, making them difficult to obtain abroad.

If possible, I would greatly appreciate it if you could provide me with the following information:

What Chinese chess textbooks (in Chinese) or classic works are commonly used by Chinese players like yourself?

Are there any authors, courses or teaching materials that are highly recommended or particularly noteworthy in China?

Could you provide me with the Chinese titles of these books or materials so that I can conduct more precise searches? If you have digital copies (PDF, images, etc.) of relevant materials and are willing to share them, I would be very grateful.

This information is of great importance to me, as I wish to directly access and study the original teaching materials and training methods that have shaped many outstanding Chinese chess players.

If you want to help just let me know and I’ll dm you.
