On May 13, 1969, Malaysia experienced its first serious racial conflict since independence. Kuala Lumpur, as the capital city and with a predominantly Chinese population at the time, saw the bloodshed occur mainly in areas where Chinese were concentrated, resulting in widespread impacts. Kampung Baru was one of the locations where riots broke out, and it was also the most concentrated area for residents of the Kuala Lumpur Engchoon community, leading to many innocent Engchoon people being affected by the racial conflict. According to government figures, Selangor state had the highest number of casualties in this racial conflict.

Following the outbreak of the May 13 racial conflict, the Kuala Lumpur Engchoon Association, seeing that many of their fellow townsmen had suffered greatly, held a board meeting on July 24, 1969, and decided to establish a Relief Commissioner Committee. Lee Yannian, the president, was appointed as the convener. Zheng Di, Qiu Xiangchi, Zhou Qingfeng, Lim Weide, Wong Mow Tong, and Wong Zhanming were appointed as seven relief commissioners responsible for fundraising and registering affected fellow townsmen. Once the registration was completed, a review was conducted, and after verification through visits, relief was distributed. To facilitate assistance to those affected by the unrest, the Kuala Lumpur Engchoon Association specifically published notices for registration procedures in newspapers.

Simultaneously, within a short period, twelve donations were collected, totaling RM 21,210. Notably, Lee Yannian and Zheng Di (under the name of the Mei Sheng Company) each donated RM 5,000, while Lim Weide (son of Lin Bangling) and Wong Long Sang donated RM 3,000 each. It is worth mentioning that the Yong Teck Association in Johor Bahru, located outside the state, also made contributions.

For Engchoon people who suffered in the May 13 racial riots, the Kuala Lumpur Engchoon Association provided assistance. At the time, there were no fewer than twenty clan associations established within the Chinese community in Kuala Lumpur. However, the Engchoon Association was among the few to publicly extend a helping hand to fellow townsmen shortly after the outbreak of the May 13 racial riots, demonstrating a rare act of solidarity among Chinese associations during that sensitive period.
