Lulu admitted that she has faced failures too. Once, she tried to connect a washing machine by converting a single faucet into a dual outlet faucet and made a mistake. She had to hire a professional to fix it, during which she learned the correct method. "Learning is a process for everyone, including myself," she said.

In fact, Lulu has recently been studying for an electrician certificate to expand her knowledge and provide more diverse content for her audience.

She acknowledges that electrical maintenance can be dangerous, and her followers may not be able to replicate it themselves. "They may still need professional assistance, but understanding the basics can save them money and trouble when hiring someone else to do the job," she said.

Lulu's most viewed video to date, posted on May 6, shows how to replace a car's windshield washer fluid and it has garnered over 774,000 views. In the video, Lulu not only demonstrates the procedure but also shares useful tips, such as recommending freeze-proof washer fluid for those living in northern China, where temperatures can drop below freezing in winter.

"Some comments question why I teach such basic tasks or if it's even worth making a video about them," Lulu said. "I admit that some of the tasks are simple, but the truth is that many girls find them intimidating because they are not familiar with gadget internals."

Lulu mentioned that she's not naturally comfortable on camera but decided to film videos to inspire other girls with the message that "we can do it".

Lulu spoke of one follower who said that she, too, had faced discouragement and criticism from her parents and society. She even began to wonder whether being a girl inherently meant she wasn't capable of fixing machines in the first place.

"I was heartened to know that watching my videos gave her the confidence to try," said Lulu.

While her channel aims to empower women, Lulu noted that some male followers also watch and learn from her, even addressing her as "sis".

"I welcome everyone to engage and communicate with me. I enjoy learning and growing alongside my followers," she said.
