It is well known that the deep inelastic scattering (DIS) and Drell-Yan (DY) processes are the key experimental approaches to reveal the partonic structure of nucleons. The Drell-Yan process is particularly important for understanding the anti-quark content and also the transverse momentum dependent (TMD) parton density functions (PDF) without the ambiguity of fragmentation process. In this talk we will report the results of flavour asymmetry of anti-quark ubar/dbar as well as the Sivers functions and Boer-Mulders functions of valence quarks in nucleons from two recent Drell-Yan experiments: E906/SeaQuest experiment at Fermilab and COMPASS experiment at CERN.
