In the presence of external magnetic field, the Kitaev model could eitherhosts gapped topological anyon or gapless Majorana fermions. In$\alpha$-RuCl$_3$, the gapped and gapless cases are only separated by athirty-degree rotation of the in-plane magnetic field vector. Thepresence/absence of the spectral gap is key for understanding the thermaltransport behavior in $\alpha$-RuCl$_3$. Here, we study the anisotropy of theoscillatory features of thermal conductivity in $\alpha$-RuCl$_3$. We examinethe oscillatory features of thermal conductivities (k//a, k//b) with fixedexternal fields and found distinct behavior for the gapped (B//a) and gapless(B//b) scenarios. Furthermore, we track the evolution of thermal resistivity($\lambda_{a}$) and its oscillatory features with the rotation of in-planemagnetic fields from B//b to B//a. The thermal resistivity $\lambda (B,\theta)$display distinct rotational symmetries before and after the emergence of thefield induced Kitaev spin liquid phase. These experiment data suggest closecorrelations between the oscillatory features of thermal conductivity, theunderlying Kitaev spin liquid phase and the fermionic excitation it holds.
