%X We study the masses of QqQq' states with JPC=0++, 1++, 1+- and 2++ in the chiral SU(3) quark model, where Q is the heavy quark (c or b) and q (q') is the light quark (u, d or s). According to our numerical results, it is improbable to make the interpretation of cncn]1++ and cncn]2++ (n=u, d) states as X(3872) and Y(3940), respectively. However, it is interesting to find the tetraquarks in the bqbq' system.
