对，沉肩抬头挺胸缩小腹，就跟京剧演员起范儿一样，这范儿一起自然而然就进入状态了。此外呢，说话语调缓和一些，别跟只鹦鹉似的，这些都是外在的辅助。内在的信心就得靠知识的内化和好心态了。

Yes, sinking your shoulders and pushing your chest out shrinks your lower abdomen. Assume the bearing of a Peking Opera actor about to perform, and once you take on these airs, they'll become natural for you. As well as this, you should speak in a milder tone, and not squawk like a parrot. These are all things that can help you externally. As for your inner confidence, for that you have to rely on internalizing knowledge and a good attitude.
