有一個小蜜蜂 飛到西又飛到東
嗡嗡嗡嗡 嗡嗡嗡嗡 不怕雨也不怕風

自立自強有信心 刻苦耐勞勤作工
萬里尋親不怕難 消滅敵人最英勇
最英勇 啦啦啦啦

有一個小蜜蜂 飛到西又飛到東
嗡嗡嗡嗡 嗡嗡嗡嗡

有恆一定會成功 有恆一定會成功
有恆一定會成功

The Adventures of Hutch the Honeybee (昆虫物語 みなしごハッチ, 1970). Quote:

The cartoon features the adventures of a young bee named Hutch: the son of a Queen bee, Hutch is separated from his mother when his native beehive is destroyed by an attack of wasps. The series follows Hutch as he searches for his missing mother, in the midst of a frequently hostile nature.

The original show (1971) is notable for its frequently sad and cruel scripts. In many episodes, Hutch would befriend another insect, only to see his new friend die a violent and painful death.

From Jason:

「小蜜蜂」卡通的主角叫做哈奇(Hutch)，是一隻年幼的小蜜蜂，某日，他所居住的蜂巢被大舉入侵的黃蜂所摧毀；幸運逃過一劫的他，卻成了一個無家可歸的流浪者。為了能找到未曾謀面的親生母親，他展開了一段漫長的冒險旅程。在這一路上，他體驗了無數的嘲諷、痛苦與悲傷；但漸漸地，他也從中學會了愛、耐心、友誼、勇氣和許多能讓生活變得更有價值的美德。

Note that Hutch the bee is a orphan, in search of his mom. In lots of these cartoons of 1970s era, the protagonist are all orphans, searching for their parent, usually mom, and going thru hardship.
