A long-standing thing is not new. It has been there for a long time: a long-standing tradition, a long-standing agreement, a long-standing problem, a long-standing friendship. The idea is that it has been in place — a custom people have kept, a deal that has lasted, a complaint nobody has really cleared up.

A long-standing thing long-standing 的東西 is not new不是新的。 It has been there for a long time它已經在那裡很久了： a long-standing tradition行之有年的傳統、 a long-standing agreement存在已久的協議、 a long-standing problem拖了多年的問題、 a long-standing friendship多年的友誼。 The idea is重點是 it has been in place它一直立在那裡—— a custom people have kept大家一直守著的習俗、 a deal that has lasted一直延續的約定、 a complaint nobody has really cleared up一直沒有人真正處理掉的抱怨。

It does not by itself say the thing is good or bad. A long-standing custom can be loved or quietly hated. The word sounds a little serious, the kind you meet in news and careful speech, but people use it in everyday talk too.

It does not by itself say這個字本身不說 the thing is good or bad那樣東西是好是壞。 A long-standing custom一個由來已久的習俗， can be loved or quietly hated可能被人喜愛，也可能被人暗暗討厭。 The word sounds a little serious這個字聽起來有點正式， the kind you meet in news and careful speech是新聞和謹慎談話裡會遇到的那種， but people use it in everyday talk too但平常聊天也有人用。

It is close to long-running, though actually they do not sit in quite the same places. Long-running likes things that keep playing out, like a show or a dispute. Long-standing likes things that have simply existed: a relationship, a rule, a habit, a grudge.

It is close to long-running它和 long-running 很接近， though actually不過其實， they do not sit in quite the same places兩個字待的位置不太一樣。 Long-running likes Long-running 喜歡 things that keep playing out一直在上演的東西， like a show or a dispute像一檔節目或一場爭執。 Long-standing likes Long-standing 喜歡 things that have simply existed單純一直存在著的東西： a relationship, a rule, a habit, a grudge一段關係、一條規定、一個習慣、一股心結。
