"60年之后，一部完全由中国基督徒学者合作翻译的“现代中文译本”圣经终於在香港出版。这批中国译者是∶许牧世、骆维仁、周联华、王成章和焦明。这个译本至今未能广泛流传。"

Please see the link below about the Chinese Bible translation history.

Since 1980's and 1990's, we have the (NT and then both NT and OT) New Chinese Translation which is being accepted by the Chinese Christian community.

You ask about the precise meaning of Matthew 24:34 (这世代还没有过去，这些事都要成就)。The key to the correct exegesis lies in the understanding of "these things" (transliterated as "panta" in original Greek Bible). We must look for the context that defines "these things". Most easily we locate the context of Jesus' famous Olivet discourse (Matthew 24-25) at the beginning of Matthew 24, verses 1 to 3:

24:1 耶稣出了圣殿、正走的时候、门徒进前来、把殿宇指给他看。

24:2 耶稣对他们说、你们不是看见这殿宇么．我实在告诉你们、将来在这里、没有一块石头留在石头上不被拆毁了。

24:3 耶稣在橄榄山上坐着、门徒暗暗的来说、请告诉我们、甚么时候有这些事．你降临和世界的末了、有甚么预兆呢。

The disciples asked Jesus TWO questions in verse 3:

Q1: 甚么时候有这些事 (meaning the startling revelation by Jesus in verse 2: the utter, flattening destructions of the Holy Temple).

Q2: 你降临和世界的末了、有甚么预兆呢

Jesus answered the second question first in his discourse (Matthew 24:4-14) and the first question afterwards (Matthew 24:15-22, also see Luke 21:20-24) before he returns to address the second question again with more revealing details (Matthew 24:23-41). In Matthew's ????ic handling of the Olivet discourse, he apparently placed Jesus' warning about the time frame of fulfilling "these things" at verse 34, mixed with Jesus' other warning about his second coming. An average reader may find it a bit mixed up on reading verse 34. This is understandable, and we see Luke's ????ic handling of the Olivet discourse is also somewhat different from Matthew's.

Lo and behold, "THESE THINGS" did happen within "this generation" then (这世代). To Jewish people, 40 years constitute one generation (that is why Saul, David, and Solomon were said to have each reigned for 40 years). In August 70AD (that is about 36 years after Jesus' Olivet discourse which happened probably on Wednesday, April 1, 33AD), Roman General Titus and his army, after many months of encircling the rebellious city, eventually broke down the resistance, slaughtered most Jews who had not died of hunger and exiled the remnant, pillaged and torched the city, burned the temple to its stone walls, and chipped open one stone after another to collect the gold melted earlier in the fire. THESE THINGS happened precisely according to Jesus' word which is also foretold by prophet Daniel some 600 years earlier (Daniel 9).

Matthew 24:15 你们看见先知但以理所说的、那行毁坏可憎的、站在圣地．（读这经的人须要会意)

24:16 那时、在犹太的、应当逃到山上．

24:17 在房上的、不要下来拿家里的东西．

24:18 在田里的、也不要回去取衣裳。

24:19 当那些日子、怀孕的和奶孩子的有祸了。

24:20 你们应当祈求、叫你们逃走的时候、不遇见冬天、或是安息日．

24:21 因为那时、必有大灾难、从世界的起头、直到如今、没有这样的灾难、后来也必没有。

24:22 若不减少那日子、凡有血气的、总没有一个得救的．只是为选民、那日子必减少了。

LUKE

21:20 你们看见耶路撒冷被兵围困、就可知道他．成荒场的日子近了。

21:21 那时、在犹太的、应当逃到山上．在城里的、应当出来．在乡下的、不要进城。

21:22 因为这是报应的日子、使经上所写的都得应验。

21:23 当那些日子、怀孕的和奶孩子的有祸了．因为将有大灾难降在这地方、也有震怒临到这百姓。

21:24 他们要倒在刀下、又被掳到各国去．耶路撒冷要被外邦人践踏、直到外邦人的日期满了。
