It is a time-honored tradition that when a temple is built, the names of the donors are literally etched in stone and stone tablets are erected on temple grounds in perpetual memory. In fact, there are such tablets inside the Khye-Sian-Ong temple in Penang; although, curiously, the first one was dated 1864. The only memorial going back to the year 1820 is again the foundation stone:
And yet, in this founding stone, the emperor's name was carved in a complete traditional character followed by a simplified character 嘉庆. Notice the 庆, instead of 大, has a 犬 inside the character. This is not a common form, and 犬 means dog, a lowly animal. In other words, this was a deliberate insult aimed at the Qing Emperor 嘉慶. The multiple mention of the year referring to 1820 also suggests a reluctance in accepting the Qing imperial calendar.
Who would have been so brazen as to create this ultimate anti-Qing expression? In that era, the Heaven and Earth secret society readily stood out.
Indeed, it is known that "早在1799年，英属槟榔屿政府就发现天地会活动的记载, i.e., as early as 1799, the British Penang Admin had discovered and recorded the activities of the Heaven and Earth Society". This statement is of immense importance. It provides the crucial extension from the past, since the 洪門天地会 or the Hong-Men branch of the 天地会 Heaven and Earth Society was linked directly to Koxinga.
Koxinga was honored as 萬雲龍 or 萬大哥 [Chief Big Brother Wan] of the society and Chen Yong-Hua [陳永華, 1634-1680 - Koxiga's political consultant and later the Prime Minister under Koxinga's son 鄭經Cheng Jing] further expanded the operation under the pseudonym 陳近南. These aliases were adopted later by the secret society to avoid detection of its anti-Qing restore-Ming activities by the Qing government and the consequential prosecution with severe punishments.
This may explain the reason why the original donors of the Jelutong temple had chosen to remain anonymous.
The Hong-Men itself was first started by Yin Hong-Seng 殷洪盛 during the rule of the last Ming Emperor of China 崇祯 Chung-zhen. After the fall of the Ming Dynasty, the fight of the Han people against the Qing invaders continued. Yin was eventually killed in action, and his son 洪旭Hong-Xu together with the remaining generals then joined Koxinga's force. And the character Hong洪 became a code word used by the members to greet one another.
To this day, branches of this now semi-secret society can still be found in Chinatowns all over the world.
