A two-letter word.

It is a general principle not to stress a word, but there are the following exceptions:

1, the triple word,, the upper part and the lower right part are mostly written as si, and the scores are not reduced, such as Xin, Sen, Miao, Zhong, Yi, Qin,? Wait a minute. The four-fold word itself forms two folds. In principle, you should give up and don't emphasize it. The other "Yan" on the lower right can be shrunk or not.

2. The root of the enclosing structure is Si, and the enclosing part itself is a composite structure with Si on the upper part. If Si shrinks to a point, it will affect the relationship between combination forms, such as meeting, sewing, jumping, crossing, occupying, jumping and so on.

3, some upper and lower structures have si, and any si is not suitable to be condensed into a point, so it is written as si, such as Yi, Yi.
