Doubts on some words in a Deng Lijun song
Here are my conclusions:


The 痴情 is supposed to be 戚戚 | qi1qi1, as suggested here;
The 仍藏心底 is supposed to be 隐藏心底 | yin3cang2 xin1 di3, as suggested here;
The 选择 at the end is supposed to be 三角 | san1jiao4, as suggested here;
The 惘然 is supposed to be 茫然; I only draw this conclusion because it seems to me "blank" fits the context better than "suddenly", since "your face is blank and there is tears in your eyes" is what would result from 茫然, whereas with 猛然 you would have "on the whole face" (一脸) and "the eyes" (眼眶), two contradictory complements of place.


The three "here"s above all link to the same link provided in Jason Swift's comment.
