Local residents and visitors on Friday said goodbye to two PLA Navy ships as they departed the city following a four-day port call.

The ships will next visit Cambodia, Thailand and Singapore.

The training vessel Qi Jiguang and amphibious landing ship Yimengshan arrived in the SAR on Tuesday and were open to the public for visits at the Ngong Shuen Chau Naval Base on Wednesday and Thursday as part of celebrations for National Day.

A farewell ceremony was held by the PLA Hong Kong garrison at 10am on Friday at the pier of the base on Stonecutters Island, where the commanding officer of the fleet thanked the SAR government and the public for their support.

Crew members were seen lining at the deck to wave goodbye to those onshore.

Enthusiastic onlookers also gathered on both sides of Victoria Harbour to bid farewell to the vessels as they sailed past.

It was the ships' first time to the SAR, and also the second time this year that the PLA Navy had come to Hong Kong and engaged in open events.

Previously, the Shandong, the country's first independently designed and built aircraft carrier, sailed into the city in July to mark the 28th anniversary of the SAR's establishment.

While the Qi Jiguang and Yimengshan docked in the city this week, a range of naval-themed activities were held, including flash mob performances and naval signal displays, attracting over 20,000 participants from Hong Kong and Macau.
