The syllable song in the words 輕鬆 (qingsong, "relaxed") and 松樹 (songshu, "pine tree") is traditionally written with different characters that indicate the two distinct meanings, but in the simplified script it is written 松 in both cases, thus eliminating the distinction.
例如麵包、麵條的「麵」，和臉面的「面」的簡體是同一個字；輕鬆的「鬆」和松樹的「松」也是同一個字。
