20 10 English version of track and field rules

I am engaged in the construction of sports facilities, that is, plastic track and artificial grass football field.

There is a new version of the track and field rules, and I want it, too.

However, it seems that the most authoritative and recent way is to mail order from the local provincial track and field association or the Chinese track and field association.

Every time it is updated, our company will buy it from China Athletics Association!
