My concern is not on 知道不知道 but more on 学业与事业 etc ..... due to the limitation in Singapore. Should we really want 新一代的年青棋手，以他作为榜样，享誉国际. May be we can have one more 郑海文 in future but at the same time if we end up with many many 年青棋手 having problem with their 学业与事业. Are we feeling happy ? As mentioned, in this way, I am not a good xiangqi promotor. This is also one of the reasons for me to move away from the promotion areas slowly...... and thinking of future direction for me too.
